Assigning arguments via strsplit() does seem to be more of a PITA, but it works now @ https://github.com/TomRoche/GEIA_to_netCDF/blob/master/netCDF.stats.to.stdout.r your assistance is appreciated, Tom Roche <tom_ro...@pobox.com> ______________________________________________ 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.
