create a pathway-microRNA(miRNA) profile and a p value matrix
Corrp2miRfile create a p value matrix and a pathway-miRNA correlation profile
choose database of pathway,"kegg","biocarta" or"reactome"
Species of miRNAs(default: hsa)
When users input interesting species and pathway, the function can calculate the p value between pathway and miRNA using hypergeometric.The p value can quantify the strength of the pathway regulated by each miRNA.The smaller p value is represent the bigger strength of regulate.Then p2m can get miRNA set(pmSET)for each pathway,which is a co-regulated miRNA set of this pathway(w>0).
A p value weighted matrix (rows are pathway ,cols are miRNAs)
pathway-miRNA correlation(pmSET) profile
