Yes, that's an R limitation. Why is it a problem? I think you would
do better using readLines if it is a line-oriented file. AFAIK that is
It would be easy to issue a warning, quite a bit harder to remove the limit
(which dates from the days when character strings were in most places
limited to 8191 chars).
