Interaction between R and Perl

béline jesson
Hello!

I'm calling R from Perl with Statistics-R perl module for a microarray
analysis integrated web tool.
I have some questions for a multi-users utilisation:
- Can I change the directory where R is running in order to have a directory
per user? Then no problem of erasing R data of an other user.
 
- If it's not possible, can I limite the number of users at the same time? I
see "lock", "is_blocked" and  "is_started" options in Statistics-R module.
How can I use them?

Thanks!

Béline

see "setwd".

Alternatively, you can have your CGI copy the R file(s) with commands to the
newly created directory, and run in there.

If your concern is one user deleting/modifying another user's data, I'd just
use setwd: it is simpler and cleaner.

We use a somewhat similar approach for our web-based applications
(www.asterias.info), which use R, and create a temporary directory for every
request.


HTH,

R.
