[Mostafa Ghaderi]

Dear R-help assistance;
may you help me regrding to following inquiry!?
you know what, i have generated three tables by xtable R function, right 
now i am trying to make a single table by putting these tables 
togethere; actully i am going to come upt with *.tex (latex) file. 
because i have more extera non-R material, i am using  Sweave to read R 
instructions, and finally i hope to end up with a single table 
containing all three tables in one table, would you let me know how i 
should go for it!?( i mean combining Sweave arguments and Latex expressions)
