Hi. I have an n x m matrix M some of who's entries are zeros. I want to know how many zeros there are in each row -perhaps stored in a 1 x n vector which lists the number of zeros for each row of M.
Before I had a vector V and I was able to get the number of zeros in V by doing length(V[ V==0]) but when I try something similar for M, like M[ M==0] it creates a vector not a matrix and so this does not work. Does anyone have a solution to this? Thank you. -- View this message in context: http://www.nabble.com/number-of-zeros-in-a-matrix--row-by-row-tp22893147p22893147.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.
