Capture output of install.packages (pipe system2)
You shouldn't assume - use file.path(R.home("bin"), "R")

Thank you, this suggestion seems to work (although I agree that starting 3 procs to install a single package seems suboptimal). One additional question: is it safe to assume that the "Rscript" executable can always be found by the R process (cross platform), or do I need to modify the example in case Rscript is not in the system search path?
