You can do

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

And if you just type

Sys.getenv()

you will see all available environment variables.

Sys.getenv() by itself produces a fairly unreadable result. You can get all of the variable names with names(Sys.getenv()), and look up those that are interesting. – Matthew Lundberg Apr 15 '12 at 19:13

You can use `as.list(Sys.getenv())` to make it more readable. – Yihui Xie Apr 16 '12 at 00:08

I prefer this

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

This works on Linux as well (tested on CentOS 6, R version 3.3) – user5359531 Feb 15 '17 at 19:58

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

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

If you're looking for the path to the current user's home directory, try:

> dirname("~")
[1] "C:/Users/username
