Dear all,

I have a data frame with different numbers of NAs in each column, e.g.:

x y
1 2
NA 3
NA 4
4 NA
1 5
NA NA

I now want to do a linear regression on y~x with all the NAs removed.
The problem now is that is.na(x) (and is.na(y) obviously gives vectors
with different lengths. How could I solve this problem?

Thank you very much for any help.

Best regards
Chris
