create a pathway-microRNA(miRNA) profile and a p value matrix

Description

The function Corrp2miRfile create a p value matrix and a pathway-miRNA correlation profile

Usage

1
Corrp2miRfile(pathway="kegg", species = "hsa")

Arguments

pathway

choose database of pathway,"kegg","biocarta" or"reactome"

species

Species of miRNAs(default: hsa)

Details

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).

Value

p

A p value weighted matrix (rows are pathway ,cols are miRNAs)

p2miR

pathway-miRNA correlation(pmSET) profile
