Rstudio: "No addins found" despite addins installed

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

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

Any idea? Thanks.

Solution

  • Edit: Seems like what might have actually fixed the issue in my case is to relocate my library path to a location with no accents, e.g., C:/Rpackages. So I first created a new folder C:/Rpackages and then copied all my current non-base packages there.

    I then used the following instructions to change my default file path:

    Installations of R will tend to install libraries at C:/Program Files/R/R-X.X.X/library, which may not always be writable. The only way to effectively change this default resides outside of R in Microsoft Windows.

    In the Microsoft Control Panel, go to System and Security > System > Advanced system settings > Environment variables.

    A new environment variable should be created by clicking on “New…” and entering R_LIBS_USER as the variable name and [your new path, e.g., C:/Rpackages] as the variable path (change as appropriate).

    Save the changes and restart R.

    enter image description here

    Then check that the library is set correctly correctly:

    > .libPaths()
[1] "C:/Rpackages"                      "C:/Program Files/R/R-4.0.5/library"

    Note: the default library will always be the one on the left, so it's displaying correctly right now. However, the one on the right cannot be changed and will display the R version you're using for base and default packages. That's OK and the issue is still fixed.

    Thanks @Bjnör for help identifying the issue.

    Old answer:

    The issue is now fixed on my end, though I am not exactly sure how. I did update Rstudio and R to the latest versions, and now the problem is gone, so it is likely that this is what solved it in my case given I don't think I have changed anything else.

    • Rstudio Version 1.4.1717
    • R version 4.0.5 (2021-03-31)
