Find windows user name within R

Question

Is there a way to get the current windows user name or the windows home within an R session?

Thanks.
(Sorry, if I missed something, but I couldn\'t find anything)

Answer 1

You can do

Sys.getenv("USERNAME")
Sys.getenv("HOME")

And if you just type

Sys.getenv()

you will see all available environment variables.

Answer 2

If you know how to do it at your system console, the answer would generally be:

system("...that_string...")

Answer 3

I prefer this

Sys.info()[["user"]]
