[R] 'system' command through Rserve

[Patil, Prasad]

Hi Jeff,

You are absolutely right. In all the mess, I forgot that my Rserve was
started by a different user! Sometimes it's the simplest solution, isn't
it? Thanks a lot.

This probably has to do with your ssh configuration and nothing to do 
with R.  How are you starting Rserve? Is it run with the same user 
privileges as when you run R manually?

Best,

Jeff
