GSEA analysis
gsea(expr, condition, cmp, geneset, plot = FALSE, power = 1)
gsea_gene_perm(s, geneset, perm = FALSE, power = 1)
The complete expression matrix
The condition labels of samples
A vector of two, cmp[1] - cmp[2] > 0
means up-regulation
A vector of genes

Power added to the weight.
A pre-sorted gene-level scores.
