It is described in the relevant manual: Writing R Extensions. ?system, and if this is Windows also ?shell and ?shell.exec. > ______________________________________________ > R-help@stat.math.ethz.ch 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.
