You can use this:
Sys.getenv("PROGRAMFILES")
or
shell("echo %PROGRAMFILES%")
shell("echo %PROGRAMFILES%", inter = T)

Hello,
I want to use the %ProgramFiles% variable in a Sys.setenv (R 2.7.2,
Windows) but it always seems to get handled literally. For instance,
in cmd.exe I get what I want
C:\Documents and Settings\user>echo %ProgramFiles%
C:\Program Files
but in R
> system("echo %ProgramFiles%")
%Pro
