[R] R error- "more columns than column names"

[Don MacQueen]

 From the help page for the read.delim() function, under "See Also", suggests:

      'count.fields' can be useful to determine problems with reading
      files which result in reports of incorrect record lengths.

This is sometimes helpful.
