I tend to do the same sort of thing.  I'll usually just comment
out the lines I want to omit.  For example, if I know that the
lines I want to omit include the string 'error', I'd use

  gawk '{ if (/error/) { print "#", $0 } else { print $0 } }' file.dat > file.dat.commented

If I want to remove any line with an NA in it, I'd use

  gawk '{ if (/NA/) { print "#", $0 } else { print $0 } }' file.dat > file.dat.commented

Then, from R, I read'em with read.table.
