plotCorrR Documentation

Basic correlation plot function for normalized or unnormalized counts.

Description

This function plots a heatmap of the "n" features with greatest variance across rows.

Usage

plotCorr(obj, n, norm = TRUE, log = TRUE, fun = cor, ...)

Arguments

obj

A MRexperiment object with count data.

n

The number of features to plot. This chooses the "n" features with greatest variance.

norm

Whether or not to normalize the counts - if MRexperiment object.

log

Whether or not to log2 transform the counts - if MRexperiment object.

fun

Function to calculate pair-wise relationships. Default is pearson correlation

...

Additional plot arguments.

Value

plotted correlation matrix
