Not able to change .libPaths?

[RobLBaker]

Hello, unforutnatley I'm not able to run my machine as an administrator so I need to change the default directory that packages are written to. I can't seem to figure out how to do this.

[1] "C:/Program Files/R/R-4.5.2/library"
> .libPaths("/C:/Users/<username>/AppData/Local/R/win-library/4.5")
> .libPaths()
[1] "C:/Program Files/R/R-4.5.2/library"
> install.packages("devtools")
Warning in install.packages("devtools") :
  'lib = "C:/Program Files/R/R-4.5.2/library"' is not writable

Any other ideas on how to change paths or why this isn't working?

(on a side not, Rstudio does have "/C:/Users//AppData/Local/R/win-library/4.5" as the default location for packages and I am able to install packages using Rstudio)

The leading / looks really odd to me here:

.libPaths("/C:/Users/<username>/AppData/Local/R/win-library/4.5")

What happens if you remove that?

Also and perhaps more importantly, I feel like the default Windows setup is to always have a user library (which you can write to) and a "system" library (which apparently you can't write to, in your case). If you restart R and inspect .libPaths() before trying to change anything, what do you see?

On my mac, if I call .libPaths() with a bad path, that silently fails, but also clobbers my user library, leaving me with just the system library. Which is what you're seeing. I suspect something similar may have happened earlier in your R session.

That does it! Of course it did. Thanks for the extra set of eyes.
