delete selecting rows and columns
Hi, I'm working with a big square matrix (15k x 15k) and I have some trouble. I want to delete selecting rows and columns. I'm using something like this: > sel_r=c(15,34,384,985,4302,6213) > sel_c=c(3,151,324,3384,7985,14302) > matrix=matrix[-sel_r,-sel_c] but it works very slow. Does anybody know how to make it in faster way? Thank's -- View this message in context: http://www.nabble.com/delete-selecting-rows-and-columns-tf3308726.html#a9203533...
