plotOncodrive {maftools}R Documentation

Plots results from oncodrive

Description

Takes results from oncodrive and plots them as a scatter plot. Size of the gene shows number of clusters (hotspots), x-axis can either be an absolute number of variants accumulated in these clusters or a fraction of total variants found in these clusters. y-axis is fdr values transformed into -log10 for better representation. Labels indicate Gene name with number clusters observed.

Usage

plotOncodrive(res = NULL, fdrCutOff = 0.05, useFraction = FALSE,
  colCode = NULL, labelSize = 2)

Arguments

res

results from oncodrive

fdrCutOff

fdr cutoff to call a gene as a driver.

useFraction

if TRUE uses a fraction of total variants as X-axis scale instead of absolute counts.

colCode

Colors to use for indicating significant and non-signififcant genes. Default NULL

labelSize

font size for labelling genes. Default 2.

Value

a ggplot object which can be further modified.
