Hi all, So let's say I have a matrix, mdat and I only know the index number. How do I retrieve the column and row names?
For example, > mdat <- matrix(c(1,2,3, 11,12,13), nrow = 2, ncol=3, byrow=TRUE, dimnames = list(c("row1", "row2"), c("C.1", "C.2", "C.3"))) > mdat[4] [1] 12 > names(mdat[4]) NULL > colnames(mdat[4]) NULL > rownames(mdat[4]) NULL > dimnames(mdat[4]) NULL Thanks ----- Lanna -- View this message in context: http://r.789695.n4.nabble.com/Retrieving-matrix-column-and-row-names-by-index-value-tp4516390p4516390.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.
