Disk quotas and permissions are helpful in case when R function depends on disk access. For other functions something more special must be devised. >> How to limit session operating memory and CPU time? > Ask he manual of your operating system. The most straightforward Linux command is ulimit which limits CPU/memory per shell/user/system wide. However, sessions are child processes of R and this requires testing whether limits will cover all sessions or each session separately. -- Kind regards, Antonio Rodriges ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
