[R] Adding argument 'flush' to read.table() too...

[Henrik Bengtsson]

What about adding the argument 'flush=FALSE' to read.table() for the option
to ignore trailing elements on each row? This feature already exists in
scan(), which is called internally by read.table():

   flush: logical: if `TRUE', `scan' will flush to the end of the line
          after reading the last of the fields requested. This allows
          putting comments after the last field, but precludes putting
          more that one record on a line.

Looking at the code for read.table(), adding argument 'flush=FALSE' and then
call scan(..., flush=flush) internally seems to be fully backward
compatible. However, I do not know about the S-Plus compatibility.

Comment: I found the need for this when trying to read TAB delimited data
files from an external software that (for unknown reasons) adds several
trailing TAB's to the last 5-10 rows.
