R help - May 2008 - Error in `[.matrix.coo`(x, rw, cl) : Subscripts out of bound

Hi All,
I am facing a strange problem.  I am making a R Package that internally run
various packages and summarizes the results from them.
I am getting this error from the piece of code written below. The text in
red color is throwing
Error in `[.matrix.coo`(x, rw, cl) : Subscripts out of bound
Value of m is 99
This code works fine when I tested it. But money I make  library it gives me
error.
I have attached the file names messages.txt which contains the
warnings/messages generated while making R package.
I am out of ideas
Kindly suggest something

regards
vidhu
