Dear R-community, I have matrices/tables of different sizes which may contain rows with only zeros. Now I would like to delete these zero lines or create new matrices composed only of the non-zero lines. Columns only containing zeros I want to preserve. Here an example:
[,1] [,2] [,3] [,4] [,5] [,6] [,7] [1,] 1 0 1 1 0 0 0 [2,] 0 0 0 0 0 0 0 [3,] 1 0 0 0 0 0 0 [4,] 1 0 1 1 1 1 1 [5,] 1 0 1 0 1 0 1 [6,] 0 0 1 1 1 1 1 [7,] 0 0 0 0 0 0 0 Rows 2 and 7 shall be deleted, but column 2 shall be maintained. I believe this should be a simple operation with basic commands, but have no idea how to manage it. Looking forward do any help, Patrick ______________________________________________ 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.
