rmarkdown syntax for tabset

[Pierre9344]

Hello,

Is it possible to use the rmardown syntax "## tab title {.tabset}" to generate tabset? It would be useful to generate tabset procedurally.
I tried the code bellow found on stackoverflow but it didn't generate tabset.

```{r, echo = FALSE, results='asis'}
headers <- c("membership", "participation")
tabs <- c("age", "gender")

for (i in headers){

    cat("###", i, "{.tabset}", "\n")
    cat("\n\n\n")

    for (j in tabs) {

        cat("####", j, "\n")
        cat("\n\n\n") 
    }
} 
```

I can use the script bellow to generate tabset for the first level (h3 title) but the next levels (h4) are not converted to tabset

::: {.panel-tabset}

```{r}
#| results='asis'
for (i in 1:nrow(ls)) {
  cat("### ", ls$VAR[i], "\n")
  load(paste0("./data/base/proposalClassification/4visits/", permut, " permut/", ls$files[i]))
  #plot(cluster_model)
  cluster_assignments <- get_clusters(cluster_model, number_clusters = 2) %>%
    dplyr::mutate(assignment_num_clus_2 = ifelse(.$assignment_num_clus_2 == 1, "A", "B")) %>%
    dplyr::rename(!!ls$VAR[i] := assignment_num_clus_2)
  colnames(df)[1] <- "ID" # rename the column v1_id
  if(i == 1) {
    original_data <- df %>% left_join(cluster_assignments, by = "ID")
  } else {
    original_data <- original_data %>% left_join(cluster_assignments, by = "ID")
  }


  cat("\n")
}
```

You have to use an extra backticks to format your document, i.e., four in your case ````.

Short answer to the question: no, you can't.

Tabset feature in Quarto is not implemented exactly as in rmarkdown.
Every level 2 headings in a cell div ::: {.panel-tabset} will be considered as a tabset, which is compatible with any procedural to write code/text as tabset (probably using knitr::knit_child() and/or #| output: asis).
Depending on your format, please read the documentation and look at the example:

• https://quarto.org/docs/output-formats/html-basics.html#tabsets
• https://quarto.org/docs/presentations/revealjs/index.html#tabsets

Thank you for the answer. I'm not sure on how to use knitr::knit_child but I have found a solution by using the cat function to print the ::: {.panel-tabset} and ::: parts

Here is an example if someone need it:

```{r}
#| output: asis
for (i in c("A","B","C")) {
  cat(paste0("### ", i, "\n"))
  cat("::: {.panel-tabset} \n")
  for (j in c("X","Y")) {
    cat(paste0("#### ", j, "\n"))
    plot(1)
    cat("\n")
  }
  cat("\n:::\n")
}
```

knitr::knit_child() is useful if you generate a code cell in a code cell and wat it to be computed.
In your case, it's "plain" text/output.

See for example: #2094 (reply in thread)

See also this specific thread with examples of how to programmatically create tabs and nested tabs : #2370

knit_child is to be used when you need to add R code content to include (like plot(1) above). It is safer to do it with knit_child() that mixing with cat() IMO. We documented that in the R Markdown Cookbook, and the recipies apply to Quarto as well.

See also https://hbiostat.org/rflow/rformat.html#quarto-report-writing-helper-functions for the maketabs function that someone has made for this kind of usage I believe.
