Arguments

maf

an MAF object generated by read.maf

vafCol

manually specify column name for vafs. Default looks for column 't_vaf'

genes

specify genes for which plots has to be generated

top

if genes is NULL plots top n number of genes. Defaults to 5.

orderByMedian

Orders genes by decreasing median VAF. Default TRUE

keepGeneOrder

keep gene order. Default FALSE

flip

if TRUE, flips axes. Default FALSE

fn

Filename. If given saves plot as a output pdf. Default NULL.

gene_fs

font size for gene names. Default 0.8

axis_fs

font size for axis. Default 0.8

height

Height of plot to be saved. Default 5

width

Width of plot to be saved. Default 4

showN

if TRUE, includes number of observations

Value

Nothing.
