Hi,
I am new to R,
I am doing quantile normalization with a dat matix of 384X124 and I find that while computing the quantile normailzation it introduces 'NA' into some of the cells, can someone help me to overcome this problem ?

This is the command that goes like upto g62 for 124 colomns

>g1 <- normalize.quantiles(exprs(MSExpr[,1:2]))

For a small set of data there is no problem, but for a large set of data, it introduces "NA" in the place where it is suppose to geneerate data .
