Defines functions f.distCol.Pearson.2

Documented in f.distCol.Pearson.2

#' Distance by correlation matrix for hierarchical clustering in heatmaps
#' Compute a matrix of distances based on Pearson's correlation. 
#' Distance is defined as dist = 1 - correlation coeficient.
#' Note that it transposes the input matrix in order to be able to use it for hierarchical clustering in heat map creation.
#' @param x A matrix of expression values
#' @param method Defults to "pearson". Can also be "kendall", "spearman".
#' @return Pearson correlation based distance object
