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 ?

>m <- read.delim(gzfile("Sample.txt.gz"), sep="\t").

> dim(m)
[1] 14 15
