Robust, platform independent method to check for python
If you can assume its on your path then try this:
pth <- sapply(strsplit(Sys.getenv("PATH"), ";"), function(x)
file.path(x, "python.exe", fsep = "\\"))
pth[file.exists(pth)][1]

Hello, I have been unsuccessfully struggling for a programmatical method to find out whether and where Python is installed. The reason is that I am developing a package that depends on python. On UNIX/UNIX-like systems I can quite safely assume that python is directly callable via system if installed. My main problems is Windows, though... Has anybody faced this problem before?
