Yes. This worked very well for what I am trying to do. The only problem I had though was figuring out why
dimnames(a) <- list(c("x","y"), LETTERS[1:4]) would not list the rows as x and y. I changed it though to letters[24:25] Thanks again Petr. -- View this message in context: http://r.789695.n4.nabble.com/Basic-matrix-manipulation-problem-tp4584734p4588042.html Sent from the R help mailing list archive at Nabble.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.
