[BioC] quantile normalization of one dataset to another

Hi,

I have two different datasets which are both originally from the
Affymetrix platform but now I only have the expression matrix.  Both
datasets have an overall different distribution of expression.  What I
would like to do is quantile normalisation on each of the experiments in
one dataset to the quantile curve of the other dataset i.e. I want to
leave the second dataset untouched, but normalise the first to it.  ANy
ideas how to do this?  I looked at normalize.quantiles but it does not
appear to do what I want.

Thanks

Dan
