Firstly, I'd hope this is the correct e-mail address to ask about specific

So, the thing with my version of R (I'm using RStudio for R x64 3.3.0 in,
currently, Windows 7) is, that I'm able to set the working directory
temporary (through using setwd() function), but once I try to set it
permanently (through "Session -> Set Working Directory -> Choose
Directory..."), this error appears: Error in setwd("~/...") : cannot change
working directory.

As I've seen online on certain forums, the problem, supposedly, is that R
in Windows is unable to recognize the ~ sign. But without it, I'm unable to
set the working directory for more than a session.

That explanation is incorrect. R in Windows simulates a Unix shell interpretation of ~ . See ?path.expand for an explanation, and run


to see how it is currently being expanded for you.

However, the fact that R interprets ~ doesn't mean it is always possible to use setwd() to go there.

It's also possible that RStudio has a bug, and is trying to change to a nonexistent directory before displaying choices to you, assuming you're getting the error before being offered the dialog to pick a directory. If that's the case, you might be able to avoid the problem by asking R to make the change:
