Hi, I have a further question about matrix manipulation.
Imagine the following two matrices: > test [,1] [,2] [,3] [,4] [1,] 1 0 6 4 [2,] 2 5 7 5 [3,] 3 6 8 6 [4,] 4 0 0 0 > matrix(is.element(test,0), ncol=4) [,1] [,2] [,3] [,4] [1,] FALSE TRUE FALSE FALSE [2,] FALSE FALSE FALSE FALSE [3,] FALSE FALSE FALSE FALSE [4,] FALSE TRUE TRUE TRUE How can I apply the TRUE FALSE matrix to the 'test' matrix so that all rows having at least one zero value will be thrown out. So after applying the TRUE FALSE matrix the test matrix shoud look like the following: [,1] [,2] [,3] [,4] [1,] 2 5 7 5 [2,] 3 6 8 6 Cheers -- View this message in context: http://www.nabble.com/Delete-rows-from-matrix-having-at-least-one-zero-value-tp20405964p20405964.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.
