maybe this should also be a FAQ because i've seen it a lot since I've
been on this list ?
assign each data.frame to a component of a list, rather than to a
component of a dataframe. you also need paste to get the number.
listDFs-list()
for ( y in 3:10 ) {
latex in Hmisc can do that with the n.cgroup= and n.rgroup= args
although if your tables are getting very complicated you might
be best off just generating the latex yourself since then you
get all the flexibility of latex.

Hi,
Dear all,
I am quite new to R; facing certain problems:
Say, I have a text file( named as try):
YearC1 C2 C3 C4 C5 C6
Y1 3.5 13.89.5 6.8 0.4 24.2
Y2 3.8 13.99.9 7.6 0.7 12.8
Y3 4.5 14.514.29.2 0.6
Dear AJSS,
The problem is that the way you've read the data, the first column of
the data frame is a factor, not a numerical variable, and thus is not
suitable for computing correlations.
You could use the command cor(idt[,-1]) to compute correlations on all
but the first column, but
