# File: cometlist.R
# Author: Tiphaine Martin
# Email: [email protected]
# Purpose: coMET.list allows the obtention of co-omic features in a region of interest.
# Version : 0.99.9
###########################################################################

#coMET allows the display of p-values from association with a correlation heatmap. 
#This version coMET.web is used for web site.

# The values given such as attributes of function erase ones of configuration file.
