It is less clear what you are after, but the canonical way to decide
if your R session is on Windows is
.Platform$OS.type == "windows"
Unlike {R.}version$os and Sys.info()["sysname"], the set of values
here is known and documented. As ?R.version does say:
Do _not_ use ‘R.version$os’ to
Not sure exactly what the original poster was after, but for
distinguishing when I am working on different machines with different
OS, I use something like this:
### Set some state variables
opSys <- Sys.info()["sysname"]
if (opSys == "Windows"){
linux <- FALSE
} else {
linux <- TRUE
}

Look at
Sys.info()

See str(version). version$platform or version$os should work for what you're
looking for.

Hi All,
I have two Rs, one has been installed in Windows

Hi,
see ?R.version
Something like
if(version$os == "mingw32") {
path = "/ABC"} else {
path = "/DEF"
}
might do it, but I'm not sure exactly what possible values version$os
can take or what determines the value exactly.

Hi Hui,
May be sessionInfo() is what you are looking for. See ?sessionInfo as well
as ?version for more details. You can run the following on your R session
and see what comes up:
sessionInfo()
sessionInfo()$R.version$platform
version$platform
Then, you might use ifelse() to set up the right pat
