R: determine if a script is running in Windows or Linux
How can an R script determine what platform it's running on? I'm using R 2.10.1, sometimes on Windows, sometimes on Linux. I would prefer a built-in function over filesystem taxonomy. I've already searched the index of the base package for anything with "os" or "platform" in the description — no dice there, alas.
回答1:
Alternatives to R.version()$os are .Platform$OS.type and R.Version()$platform. See ?.Platform for further info. Note that Sys.info() is not implemented on all platforms, but does give the key information on which platform R is running whereas the others give info on the platform under which R was built.
回答2:
You can use R.Version()$os
