Hi,
I have a n*m matrix and would like to count the number of elements not equal to
NA in a ROW.
e.g.
x 1 2 3 NA 10
y 2 NA 8 9 NA
Which function can I use to obtain
4 for row x and
3 for row y?
Could you help me? I found some functions for columns but not for rows...
Thank you very much!
Try this:
rowSums(!is.na(x))
