I had documented a few problems I found in R here: http://r-proto.googlecode.com and you might want to go over them. The item you mention is discussed in #1 there. This was written some time ago and there may have been relevant changes to R since then so it would be a good idea to double check everything with the current version of R. ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
