Re: [R] How do I know where is R? - VB Programming
This works on Linux (at least under bash shell) and also on Windows Vista and presumably earlier versions of Windows as well: R --vanilla --slave -e R.home() but the R part at the beginning does have the problem that it only works if R is on your path. If, on Windows, you normally double click the R icon on your desktop or use the R utilities in the batchfiles distribution there would be no need to have R on your path. The batchfiles utilities use the registry, and failing that heuristics, to locate R.

For some examples of using the R registry entries see Rcmd.bat, Rversions.bat and Rversions.hta in the batchfiles distribution whose home page is: http://batchfiles.googlecode.com On Tue, Jul 14, 2009 at 7:22 PM, Haoda Fufu...@yahoo.com.cn wrote: Dear all - Is there anyone know how to let VB or C# know where I install R automatically(i.e. auto detect R directory)?
