Generate histogram plot(s) of permutation test results

Source: R/PlottingUtils.R
plotHistogram.Rd

This function takes the output from function permuteDE and creates a histogram plot showing the permutation test result for each indicated split. Each histogram includes a vertical line at the observed number of DE features in the unpermuted "true" comparison.

Usage

plotHistogram(
  input,
  use_splits = NULL,
  title = NULL,
  subtitle = NULL,
  label_pvalue = TRUE
)

Arguments

input

Output from function permuteDE.

use_splits

A character string or vector containing the names of splits to use. Defaults to NULL, which will try all splits.

title

Character string indicating the plot title. Default = NULL sets a title automatically for each split.

subtitle

Character string indicating the plot subtitle. Default = NULL automatically generates a subtitle.

label_pvalue

A Boolean value indicating whether to label the permutation test p-value. Defaults to TRUE.

Value

If only one split is provided, a single ggplot2 object, otherwise a named list of ggplot2 objects, where each element corresponds to a split.
