Adding two or more columns of a data frame for each row when NAs are present.
...ch row in
mySum? NA should be treated as a 0. Please, note, I do not want to sum all
the columns, as I think rowSums would do, just the selected ones.
Thanks for your help.

Rebuild of kernel 2.6.9-67.0.20.EL failure
Hello list.
I'm trying to rebuild the 2.6.9.67.0.20.EL kernel, but it fails even without
modifications.
How did I try it?
Created a (non-root) build environment (not a mock )
Installed the kernel.scr.rpm and did a
rpmbuild -ba --target=`uname -m` kernel-2.6.spec 2> prep-err.log | tee
prep-out.log
The build failed at the end:
Processing files: kernel-xenU-devel-2.6.9-67.0.20.EL
