About dropping the ñ, (I did understand is like a joke), I want to say I'm not a windows user but almost all of my students are, and I don't
want this prevent them to use R.


I want to notice that USERPROFILE is correctly set:
> Sys.getenv("USERPROFILE")
[1] "C:\\Users\\Muñoz"
> Sys.getenv("R_USER")
[1] ""
> Sys.getenv("HOME")
[1] ""

At the end the more output info.

Should I include this as a bug in R's Bugzilla or is enough to put here?

Best, Manuel.
