plotNoiseModel function

Function for plotting the baseline model of gene expression variability

This function plots the variance against mean expression across all genes and a second order polynomial to the base line of the variance-mean dependence in log space.

plotNoiseModel(x, corrected = FALSE)

Arguments

• x: List object returned by function noiseBaseFit or function compNoise.
• corrected: logical value. If TRUE, then the variance is plotted after regressing our the mean dependence.

Returns

None

Examples

x <- noiseBaseFit(intestinalDataSmall,step=.01,thr=.05)
plotNoiseModel(x)
