I have a number of text files that were archived by gzip. To save the
trouble of uncompressing them, I used the following command. Then I
checked the dimension of m, the number of rows is 14 which should be
10000. How can I "force" the remaining rows to be read into m ?
[1] 14 15
R version 2.8.0 (2008-10-20)

What did the data appear like when it was read in?  Have you just
tried to read in the lines (readLines) to see if the decompression is
working?  Does this compare to what you get if you decompress the file
outside of R?  Not exactly sure what you mean by "force" since the
command it probably reading in what it thinks is a complete file.  Are
there characters in the file that might cause it to stop reading, or
to bunch up data differently (e.g., misplaced quotes).

Some more information has to be provided to guess what your problem might be.
