Dear List, Hi! I am wondering what is the simplest way to subset a portion of columns from a matrix.
For example, there is a matrix A (238,304*243). What is the simplest way to get a sub-matrix B which comprises of column 1, 3, 5, 7,9,...(odd column number) from matrix A? Thank you very much for your help! Best, Allen ______________________________________________ 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.
