PlotUTRLengthShift: Plot global shifts in 3'UTR length

In VCCRI/Sierra: PolyA counting and differential transcript usage analysis for scRNA-seq data

Plot global shifts in 3'UTR length

Description

Plot global shifts in 3'UTR lengths between cell populations. Input is a table of results from the Detect3UTRLengthShift functions. By default evaluates whether there is a significant shift in 3'UTR length between upregulated and downregulated peaks using the Wilcoxon Rank-sum test.

Usage

PlotUTRLengthShift(
  results.table,
  plot.title = "Global shift in 3'UTR length",
  do.ranksum.test = TRUE,
  return.plot = TRUE,
  do.plot = FALSE
)

Arguments

results.table	table produced by the DetectUTRLengthShift function
plot.title	optional title
do.ranksum.test	whether to perform a ranksum test on the shift in UTR usage
return.plot	whether to return the ggplot2 object
do.plot	whether to print the figure to output

Examples

extdata_path <- system.file("extdata",package = "Sierra")
results.file <- paste0(extdata_path,"/Cycling_vs_resting_fibro_UTR_length_res.RData")
load(results.file)

PlotUTRLengthShift(res.table)
