plot_pval_hist: Plot a histogram of p-values
In FireGutter/geneference: Simulating and analysing genes with LT-FH

Description Usage Arguments Details Value

Creates a histogram of the specified p-values.

plot_pval_hist(
  dataset,
  P,
  bins = 20,
  line_color = "black",
  fill_color = "cornflowerblue",
  mean_color = "red",
  save_plot_path = FALSE,
  plot_filename = "pvalue_histogram.png"
)

`dataset`	data imported to R by `load_results()`.
`P`	column containing p-values to be plotted. State in the format dataset$P_value.
`bins`	number of bins used.
`line_color`	outline color of bins.
`fill_color`	fill color of bins.
`mean_color`	color of the line showing the mean value.
`save_plot_path`	if `FALSE`, return the function returns a ggplot object. Else a path of the directory to save the plot to.
`plot_filename`	name of the file to be saved, including file extension. Must be either .pdf, .png or .jpeg

Use analysis_association() to obtain p-values for an analysis and import these with load_results().
The function also draws a line on the y-axis showing the mean of the p-values.
vignette("ggplot2-specs", package = "ggplot2") details the usage of aesthetic parameters in ggplot2.

Either returns a ggplot object or saves the plot to save_plot_path and returns NULL.
