Thank you, this suggestion seems to work (although I agree that starting 3 procs to install a single package seems suboptimal).
For something that I only do every few weeks or months, I'd rather optimize the use of the programmer's time than that of the processor. I get paid more per hour! Duncan Murdoch 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?
