sex_distribution_heatmap: Sex distribution heatmap

In RomainFeron/radsex-vis: Visualization of results from the RADSex pipeline

Description

Generates a heatmap of the distribution of sequences between two populations. In the resulting heatmap, the color of a tile at coordinates (x, y) indicates the number of sequences present in x males, on the horizontal axis, and y females, on the vertical axis.

Usage

sex_distribution_heatmap(data, title = NULL, show.significance = TRUE,
  significance.color = "red3", significance.threshold = 0.05,
  color.scale.bins = c(0, 1, 5, 25, 100, 1000),
  color.scale.colors = c("white", "navyblue"))

Arguments

data	A table of distribution of sequences between sexes obtained with the load_sex_distribution_table function.
title	Plot title (default NULL).
show.significance	If TRUE, tiles with significant association with sex are highlighted with the color defined in the significance.color parameter (default TRUE).
significance.color	Color of the border for tiles significantly associated with sex (default "red3").
significance.threshold	P-value threshold to consider a tile significantly associated with sex (default 0.05).
color.scale.bins	A vector of values to use as bins in the color palette (default c(0, 1, 5, 25, 100, 1000)).
color.scale.colors	A vector of two colors used to create the color palette gradient default (c("white", "navyblue")).

Value

A heatmap stored in a ggplot object.

Examples

heatmap <- sex_distribution_heatmap(data, title = "Distribution of sequences between sexes",
                                    significance.color = "blue", significance.threshold = 0.01,
                                    color.scale.bins = c(0, 10, 100, 1000),
                                    color.scale.colors = c("white", "red3"))
