[BioC] GSEA test by gene permutation instead of phenotype permutation

[Yuan Hao]

Dear list,

I know there is a gseattperm() function available in the Category  
package used to perform GSEA test on two group of samples. The  
permutation is based on phenotype labels of the samples. I am  
wondering is there a similar function can be used to do the same test,  
but based on the permutation of genes because I have a very small  
number of samples ( 6 samples in total for two phenotypes ( 4 versus  
2) ). If not, may I get around this problem by transposing my data set  
to use the gseattper() by permuting on genes? Thank you very much in  
advance!

Kind regards,
Yuan
