[R] how to run R as a daemon

[Laurent Faisnel]

Hi all,
Using R a as a real-time application called by Php for a website, I 
would like to run one R process only, which would manage user 
connections. For the time each user who asks for an analysis causes a 
new R process to start, which is not suitable in prevision of many 
users. R needs about 30 seconds to run the script which makes the 
analysis. The problem is that this waiting time is n times more 
important when n users ask for an analysis...
Thanks for any help.

Laurent
