But, if you are running several R sessions with complex tasks, well, then I have an humble question: Why do you are using TM for that? You want to control all R sessions with TM?
Hans,
I THINK that what Haris meant was that you may have the WORKSPACE from the different running R sessions getting mixed up.. Whereby potentially some variables are being created by one session and wrongly evaluated by another session that thinks they are part of that session. I for one am one of those that frequently runs 3 instances of R all from TM - sometimes (almost) simultaneously: the R version; the Sweave version; and the Console version (this more for the simple one off calculations say as I work in my latex/ Sweave document - infact, at times the calculation has nothing to do with the work - but someone calls while I am in the middle of work & presents a set of figures - eg a debt that I quickly need to work out). So I would care that the potential mess up that Haris mentions does not occur because of something lying around/defined in the workspace by one or the other of these different environments. And yes, I know that I can use the maths bundle for some calculation, but I for one feel comfortable using R even for these since I can save the variables eg if I am doing sample size calculations.
