Problem with read.table()

Dear all,

I have encountered a strange problem with read.table().

When I try to
read a tab delimited file I get an error message for line 260 not being
equal to 14 (see below).

Using count.fields() suggests that a number of lines have length not
equal to 14, but not 260.

Looking at the actual file, however, I cannot see anything wrong with
any lines. They all seem to have length 14, there are no double tabs
etc., and the file reads correctly in other programs. Does anyone have
any suggestions as to what this might stem from?

I have placed a copy of the file at
http://dss.ucsd.edu/~kgledits/archigos_v.1.9.asc

regards,
Kristian Skrede Gleditsch
