See ?dim and ?prod Be aware that a vector (eg. 1:5) will be 'dim-less', thus if you are going to use this approach for a vector based data object, you would want to use ?length Regards, Marc Schwartz ______________________________________________ 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.
