http://tolstoy.newcastle.edu.au/R/help/04/11/6887.html Slightly adapted (mydata <- data.frame(matrix(c(1,2,3,4,5,6,7,8, NA),3))) mydata[apply(mydata, 1, function(x)!any(is.na(x))), , drop=TRUE]
But if i want to omit rows or cols with i.e . >20% missing> values, could?t find any package-based command, probably because it is to simple for anyone to do that manually, though not for me. Can anyone please help me ? - vickie
I'd have to think about this. Hopefully a guru can come up with something quickly.
