[BioC] How to create expression data packages

[Srinivas Iyyer]

Dear group, 
 I have 15 gene expression studies.  I have raw data
for these (some are GEO datasets). 

I could make esets for these datasets. 

i want to create  expression data packages, so that my
peers can also use these datasets for their analysis. 

I have the following components for each dataset:
1.phenoData
2.expression data matrix
3. detailed annotations including clinical variables
embeded into phenoData. 

I could make an eset for these:

eset <- new('exprSet',data = exp.mat, phenoData=pheno)

from now on how can I go ahead and make expression
data library. 

Is there any step-by-step procedure to create a
experimental data library. 

could any one pls. help me.

thanks
