Hi all, I want to ask that how to create column names for a matrix. For example, the matrix below, the column names should be: 1-A, 1-B, 1-C, 1-D, 2-A, 2-B, 2-C, 2-D, 3-A, etc. Thanks for your help.
chars = c('A','B','C','D') matrix1 = matrix(nrow = length(1:100), ncol = length(1:5)*length(chars)) k = 0 for(i in seq(1:length(1:5))){ for(j in seq(1:length(chars))){ k = k+1 matrix1[,k] = c(1:100)[k] } } [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see 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.
