Error: 'filter' is not an exported object from 'namespace:duckplyr

[shahronak47]

So I was on duckplyr package version 0.4.1 where everything works as expected for me. I have recently upgraded the package to 1.0.1 and now running the same code I am getting

Error: 'filter' is not an exported object from 'namespace:duckplyr

What has changed and how can I solve it?

Thanks, good question. The most important related change is that duckplyr no longer reexports all of dplyr's functions and methods. For writing a script, this should be of little relevance because duckplyr still depends on dplyr. See the "Loading required package" in the output:

options(conflicts.policy = list(warn = FALSE))
library(duckplyr)
#> Loading required package: dplyr
#> ✔ Overwriting dplyr methods with duckplyr methods.
#> ℹ Turn off with `duckplyr::methods_restore()`.

^{Created on 2025-03-02 with reprex v2.1.1}

For packages and other more advanced setups, you now need to import filter() from the dplyr namespace, perhaps using roxygen2:

#' @importFrom dplyr filter
NULL

Do you think our documentation needs more work here?

I haven't looked it up in the documentation. I tried to find it in NEWS.md file but at that time didn't find any relevant changes. Now looking back I can find the changes in the NEWS file. Thank you for your response.

Out of curiosity, what was the motivation behind this change?

Reexporting leads to ugly duplicates when ?filter or ?mutate is requested in the RStudio IDE.
