SomaticSignatures (version 2.8.4)

mutation-distribution: Distributions of mutational locations.

Description

Summary and plotting function for characterizing the distributions of mutations along the genome.

Usage

mutationDistance(x)
plotRainfall(x, group, size = 2, alpha = 0.5, space.skip = 0, ...)

Arguments

x

A 'GRanges' or 'VRanges' object [required].

group

The variable name for color groups [optional].

size

Point size [default: 2]

alpha

Alpha value for points [default: 0.5]

space.skip

Space between chromosomes, as defined by 'plotGrandLinear' [default: 0]

...

Additional arguments passed to 'plotGrandLinear'

Value

• mutationDensityThe position-sorted GRanges 'x' with the additional column 'distance', specifying the distance from the previous mutation (or the beginning of the chromosome if it happens to be the first mutation on the chromosome.)
• plotRainfallObject of class 'ggbio', as returned by 'plotGrandLinear'.

Examples

library(GenomicRanges)
library(IRanges)

set.seed(1)
chr_len = 100
gr = GRanges(rep(1:3, each = 10),
  IRanges(start = sample.int(chr_len, 30, replace = FALSE), width = 1),
  mutation = sample(c("A", "C", "G", "T"), 30, replace = TRUE))
seqlengths(gr) = rep(chr_len, 3)

p = plotRainfall(gr)
print(p)
