Motivation

Merging relational data

Consider following tables orders, order_items, products, customers connected with join keys
following sql convention {child}.{$parent}_id = {$parent+"s"}.id, for example
orders.customer_id = customers.id. teal.data setup would look like this:

Sample data setup with relational tables and join keys

Imagine now a scenario of a ggplot where one wants to select x, y, color, facet_rows,
facet_cols from any variable in any dataset.

Example ggplot with dynamic variable selection

ggplot(
  data = ?,
  aes(
    x = !!sym(input$x), # orders.order_date
    y = !!sym(input$y), # order_items.total_price
    color = !!sym(input$color) # products.category
  )
) +
  geom_line() +
  facet_grid(
    vars(!!sym(input$facet_rows)) # customers.country
  )

In order to create above visualization, datasets need to be merged as ggplot::aes is related to single
data object. Problem is solvable as teal.data has enough information to determine correct
merge call based and selected variables and join_keys (describing relationships between datasets).

Using dplyr only we need to perform following merge operation given that following variables have
been selected:

x: orders.order_date
y: order_items.order_items.total_price
color: products.category
facet_rows: customers.country

Merge operation using dplyr joins

data_w_merged <- within(data, {
  anl <- dplyr::select(orders, id, customer_id, order_date) %>%
    dplyr::left_join(dplyr::select(order_items, order_id, product_id, total_price), by = c(id = "order_id")) %>%
    dplyr::left_join(dplyr::select(products, id, category), by = c(product_id = "id")) %>%
    dplyr::left_join(dplyr::select(customers, id, country), by = c(customer_id = "id"))
})

Now anl can produce desired visualization

Creating visualization with merged dataset

# Create the visualization with merged data - sum moved to ggplot
data_w_plot <- within(data_w_merged, {
  library(ggplot2)

  # Create ggplot with sum calculation inside
  plot <- ggplot(
    data = anl,
    aes(
      x = order_date,
      y = total_price,
      color = category
    )
  ) +
    geom_line() +
    facet_grid(
      rows = vars(country),
      labeller = label_both
    )
  
  print(plot)
})

get_outputs(data_w_plot)[[1]]

Handling ambiguous variables

When merging datasets containing duplicated variable names dplyr::*_join(suffix = c(".x", ".y")) automatically
adds a suffix to the columns, so that names are alway unique.

Merging interactively

Developing system which can interactively handle merge is a challenging task not only for a reasons described above
but also due to additional layers which need to control described operation. These layers include:

Providing an API for app-developer to enable and set specific merge configuration.
Handling reactive relationship between all inputs (dataset -> variable -> value) and avoid unnecessary triggers.
Providing robust, easy to use merge-modules which can handle weirdest app-developer needs (1) and provide meaningful information to the app-user about consequences of the data/variable selections.

1. Configure possible selection

picks and choices/selected

We came with an idea of picks which allows app-developer to specify datasets, variables and values to be
selected by app-user during an app run. Each of them is based on the idea of choices/selected where app-developer
provides choices and what is selected by default. App-user though changes selected interactively.

graph TB
    subgraph AppDeveloper["👨‍💻 App Developer (Configuration Time)"]
        Dev[App Developer]
    end

    subgraph Variables["variables()"]
        VAR_Choices["choices"]
        VAR_Selected["selected"]
    end

    subgraph AppUser["👤 App User (Runtime)"]
        User[App User]
        UI["selectInput<br/>(UI Component)"]
    end

New design bases on an idea that a module can consume its arguments referring to any variable in any dataset. Consider following example, where:

a module uses x, y and facet arguments to create an interactive inputs,
user can select a variable from any dataset for x, y, facet
visualization will be build on a merged dataset containing these three variables.

# pseudocode
tm_example <- function(x, y, facet) {
  ui = function(id, x, y, facet) ...., # inputs will be here
  server = function(id, x, y, facet) {
    moduleServer(id, function(input, output, session) {
      output$plot <- renderPlot({
        merged_dataset |>
          ggplot(
            aes(
              x = <selected x var>,
              y = <selected y var>
            )          
          ) + geom_point() + facet_wrap(vars(<selected facet var>))
      })
    })
  }
}

To provide choices and default selection for x, y and facet we propose following api:

Proposed API using picks() for variable selection

# pseudocode
tm_example(
  x = picks(
    datasets(<choices>, <selected>),
    variables(<choices>, <selected>)
  ),
  y = picks(
    datasets(<choices>, <selected>),
    variables(<choices>, <selected>)
  ),
  facet = picks(
    datasets(<choices>, <selected>),
    variables(<choices>, <selected>)
  )
)

Where each function creates an object which holds the information consumed by the framework. choices and selected can be either:

tidyselect selection_helpers (?tidyselect::language)
Integer denoting index of column(s)
explicit character denoting the name of the objects/columns/level

Relationship between `picks` elements

Each picks element is evaluated in a sequence starting from datasets. selected in one of them determines possible choices of the next one. For example:

If datasets is selected to be iris, then following variables's choices will be variables of iris. selected can't be something else than a choices and so on.

graph TB
    subgraph "picks()"
        subgraph "datasets()"
            DS_Choices["choices<br/>(available datasets)"]
            DS_Selected["selected<br/>(chosen dataset)"]
        end

        subgraph "variables()"
            VAR_Choices["choices<br/>(available variables)"]
            VAR_Selected["selected<br/>(chosen variable)"]
        end
    end

    DS_Choices -->|"user selects from"| DS_Selected
    DS_Selected -->|"determines"| VAR_Choices
    VAR_Choices -->|"user selects from"| VAR_Selected

    DS_Selected -.->|"e.g., if 'iris' selected"| VAR_Choices
    VAR_Choices -.->|"then choices become<br/>iris columns"| VAR_Selected

    class DS_Choices,VAR_Choices choicesStyle
    class DS_Selected,VAR_Selected selectedStyle

    style DS_Selected stroke-width:3px
    style VAR_Choices stroke-width:3px

Example settings

Please read carefully the code and see the description to understand how picks work.

Strict variables picks

picks below will create an input in the module where single variable can be selected from c("Sepal.Length", "Sepal.Width"). multiple = FALSE disallow user to select more than one choice.

Example: Strict variable picks with single selection

picks(
  datasets(choices = "iris", selected = "iris"),
  variables(choices = c("Sepal.Length", "Sepal.Width"), selected = "Sepal.Length", multiple = FALSE)
)

Dynamic variables choices

Following picks will create an input in the module where user will be able to select any variable from iris (any = everything()) and by default 1-st will be selected. Be careful, setting explicit selected when choices throws a warning as it is not certain for example that "Species" %in% everything().

Example: Dynamic variable choices with tidyselect

picks(
  datasets(choices = "iris", selected = "iris"),
  variables(choices = tidyselect::everything(), selected = 1, multiple = FALSE)
)

Dynamic variables from multiple datasets

Consider a situation when one wants to select a variable from either iris or mtcars. Instead of forcing app-developer to enumerate all possible choices for iris and mtcars. Following picks will create two related inputs for datasets and for variables. Input for variables will automatically update when dataset selection changes.

Example: Multiple datasets with dynamic variables

picks(
  datasets(choices = c("iris", "mtcars"), selected = "iris"),
  variables(choices = tidyselect::everything(), selected = 1, multiple = FALSE)
)

Dynamic everything

In extreme scenario also lists of datasets could be unknown. Or to avoid writing too much text, one can specify following picks.

Example: Fully dynamic dataset and variable selection

picks(
  datasets(choices = tidyselect::where(is.data.frame), selected = 1),
  variables(choices = tidyselect::everything(), selected = 1, multiple = FALSE)
)

Implementation in `teal_module`

teal_module will accept x, y and facet and hand-over them to both ui and server.

Module definition with picks arguments

tm_example <- function(x, y, facet) {
  module(
    ui = ui_example,
    server = srv_example,
    ui_args = list(x = x, y = y, facet = facet),
    server_args = list(x = x, y = y, facet = facet)
  )
}

On the ui part it is necessary to call picks_ui for each picks object.

UI implementation with picks_ui

ui_example <- function(id, x, y, facet) {
  ns <- NS(id)
  div(
    picks_ui(id = ns("x"), picks =  x),
    picks_ui(id = ns("y"), picks =  y),
    picks_ui(id = ns("facet"), picks =  facet),
    plotOutput(ns("plot"))
  )
}

In the server, picks are utilized in picks_srv which can be called per each pick, or for all at once (as in the example below). picks_srv is used only to resolve dynamic choices/selected and to handle interaction between inputs. selectors contain a list of selected datasets/variables for each pick. In this example selectors structure looks like this:

x: (reactiveVal)
  datasets: 
    choices: ...
    selected: ...
  variables: 
    choices: ...
    selected: ...
y: ...
facet: ...

To create a merged-dataset using information from app-user selection one needs to call merge_srv. picks_srv doesn't do anything else than controlling a selection for a number of reasons:

One might want to use different set of variables to perform merge. For example, some might be controlled with picks_ui/srv and have an UI element and some might be fixed and added optionally to the merge_srv(selectors).
Before merge is performed, one might want to validate if the selection is correct from a module perspective.

merge_srv returns a list with two reactives:

data: teal_data object with merged dataset and
merge_vars: named list of variables. List is named after selector name, for example merge_vars()$facet

Server implementation with merge_srv

srv_example <- function(id, data, x, y, facet) {
  moduleServer(id, function(input, output, session) {
    selectors <- picks_srv(data = data, picks =  list(x = x, y = y, facet = facet))

    merged <- merge_srv("merge", data = data, selectors = selectors)

    plot_q <- reactive({
      within(merged$data(),
        {
          merged %>%
            ggplot(aes(x = x, y = y)) +
            geom_point() +
            facet_wrap(vars(facet))
        },
        x = str2lang(merged$variables()$x),
        y = str2lang(merged$variables()$y),
        facet = str2lang(merged$variables()$facet)
      )
    })

    output$plot <- renderPlot({
      req(plot_q())
      rev(get_outputs(plot_q()))[[1]]
    })
  })
}

a filtering mechanism.

    select = select_spec(
      choices = c("Sepal.Length", "Species"),

# to picks and transformators

    selected = 1L
  )
)

# Apply filtering through teal_transform_module
transformators = teal_transform_module(
  ui = function(id) {
    ns <- NS(id)
    selectInput(
      ns("species"),

      choices = c("setosa", "versicolor", "virginica"),
      selected = "setosa"

  server = function(id, data) {
    moduleServer(id, function(input, output, session) {
      reactive({
        req(input$species)
        within(
          data(), {
            iris <- iris %>% dplyr::filter(Species %in% !!filter_values)
          }, 
          filter_values = input$species)
      })
    })
  }
)

Conversion from to data-extract-spec

picks will completelly replace data_extract_spec (des) and will be the only tool to select-and-merge
in teal framework. So far des will be supported as soft deprecated. help("as.picks")
contains the information how to convert des into picks but in a limited scope.

data_extract_spec (or a list of des) containing only select_spec are convertible 1:1 to the picks
filter_spec is not convertible to picks as it variables used in filter can be different than variables selected in select_spec, thus hierarchical form of picks can't handle this case.
filter_spec can be converted to teal_transform_module and used in transformators argument instead and we recommend to do so. teal.transform::teal_transform_filter provides a simplified way to create such transformator.

Issues with `data_extract_spec`

API of data_extract_spec is bad encapsulation, hard to extend, confusing and easy to break.

Bad encapsulation

In filter_spec one can specify choices = value_choices(dataname, subset = function(data)), this is vulnerable
for multiple failures:

value_choices("dataname") can be completelly different than data_extract_spec(dataname), guess what happens? ;]
subset = function(data) is a function of a dataset, it means that even if vars = "Species" has been provideed one still have to do levels(data$Species) instead of levels(column)

As you can see, there are few places where scope of the classes is not well separated which leads to:

repeating same information on multiple levels of the hierarchy data_extract_spec(dataname) and value_choices(dataname), vars = "Species", levels(data$Species)
Repeating the same information also requires to be cautious to have both places correctly specified, otherwise error will occur

data_extract_spec(
  dataname = "iris",
  select = select_spec(
    choices = variable_choices(subset = function(data) names(data))
    selected = "Sepal.Length"
  ),
  filter = filter_spec(
    vars = "Species",
    choices = value_choices("iris, subset = function(data) levels(data$Species)),
    selected = first_choice()
  )
)

Conclusion:

value_choices(data) shouldn't have an argument data as it is "given" by the data_extract_spec. Same applies to variable_choices(data).
value_choices(subset = function(data)) should be a function of column which is set in filter_spec(vars)

Hard to extend

Recently one user asked to make data_extract_spec(datanames) delayed, so that it will adjust automatically to the existing datasets when resolved. Problem is API allow to have des for multiple datasets only when one knows their names. It is just done by making a list-of-des. Following code will produce dropdown with "iris" and "mtcars" and app-user will be able to switch between datasets (switching between des)

# pseudocode
list(
  data_extract_spec(dataname = "iris", ...),
  data_extract_spec(dataname = "mtcars", ...)
)

Proposition was that dataname = dataset_choices(), similar to the filter_spec(vars = variable_choices()). Let's consider how would it look like:

data_extract_spec(
  dataname = dataset_choices(choices = all_datasets(), selected = first_choice()),
  select = select_spec(
    choices = variable_choices(dataname = ??, choices = function(x) names(data))
  )
  filter = filter_spec(
    vars = variable_choices(dataname = ??, choices = function(x) names(data)), # how to obtain delayed `dataname`
    choices = value_choices(dataname = ??, choices = function(x) data$?? |> levels()) # how to obtain delayed `vars`
  )
)

To achive this, package would have to be seriously refactored, to be able to do following:

data_extract_spec(
  dataname = dataset_choices(choices = all_datasets(), selected = first_choice()),
  select = select_spec(
    choices = variable_choices(choices = function(x) names(data))
  ),
  filter = filter_spec(
    vars = variable_choices(choices = function(data) names(data)),
    choices = value_choices(choices = function(column) column |> levels())
  )
)

Let's just use above example and change function names:

picks(
  datanames(choices = all_datasets(), selected = first_choice()),
  variables(
    choices = variable_choices(choices = function(x) names(data))
  ),
  values(
    vars = variable_choices(choices = function(data) names(data)),
    choices = value_choices(choices = function(column) column |> levels())
  )
)
