"No addins found"

Hi, I'm trying to install Rstudio addins, but they don't show up in the Addins button or Tools → Addins → Browse Addins... menu. I first updated my Rstudio, and then reinstalled again, to no avail.

This is how I proceed:

devtools::install_github("rstudio/addinexamples", type = "source")

It installs successfully (and I can check that it appears correctly in the package tab or in C:\Users\USERNAME\Documents\R\win-library\4.0\addinexamples) but still does not show up under the addins button. Username has special characters though (French accents). Would that be the problem?

Even after loading the library manually as so:

library(addinexamples)

The library appears loaded but no button. I tried many other packages with the same result (e.g., addinmanager, addinslist, colourpicker, esquisse). Any idea? Thanks.

Hi @RemBoy,
You could try several things:
Upgrade to R-4.0.3 to see if that changes anything.
Try installing an addin package from CRAN which does not need compiling e.g. {datapasta}.
Check that the RStudio addin registration file has not been lost/corrupted - see details here:
http://rstudio.github.io/rstudioaddins/

Thanks for your answer @DavoWW!

I already tried installing packages from CRAN directly with the same results. E.g.,

install.packages("datapasta")
package ‘datapasta’ successfully unpacked and MD5 sums checked

I couldn't find the file inst/rstudio/addins.dcf within C:\Program Files\RStudio but I did find it in each library's folder e.g, Documents\R\win-library\4.0\addinexamples\rstudio. So I'm not sure why it would be corrupted since I tried reinstalling the packages, and several of them. (How do you check if the file is corrupted? If it's only reinstalling, then that's been done) File contains:

Name: Insert %in%
Description: Inserts `%in%` at the cursor position.
Binding: insertInAddin
Interactive: false

Name: Find and Replace
Description: Find and replace words in a document.
Binding: findAndReplaceAddin
Interactive: true

Name: Reformat R Code
Description: Reformat R code using 'formatR::tidy_source()'.
Binding: reformatAddin
Interactive: true

Name: Subset a Data Frame
Description: Interactively subset a data frame.
Binding: subsetAddin
Interactive: true

Finally, I just updated R to 4.0.3, and I still experience the same problem.
