In ORFik: Open Reading Frames in Genomics

Description

Coverage heatmap of single libraries

Usage

heatMap_single(
  region,
  tx,
  reads,
  outdir,
  scores = "sum",
  upstream,
  downstream,
  zeroPosition = upstream,
  returnCoverage = FALSE,
  acceptedLengths = NULL,
  legendPos = "right",
  colors = "default",
  addFracPlot = TRUE,
  location = "start site",
  shifting = NULL,
  skip.last = FALSE,
  title = NULL
)

Arguments

region	#' a GRangesList object of region, usually either leaders, cds', 3' utrs or ORFs, start region, stop regions etc. This is the region that will be mapped in heatmap
tx	default NULL, a GRangesList of transcripts or (container region), names of tx must contain all grl names. The names of grl can also be the ORFik orf names. that is "txName_id"
reads	a GAlignments or GRanges object of RiboSeq, RnaSeq etc. Weigths for scoring is default the 'score' column in 'reads'
outdir	a character path to save file as: not just directory, but full name.
scores	character vector, default "sum", either of zscore, transcriptNormalized, sum, mean, median, .. see ?coverageScorings for info and more alternatives.
upstream	an integer, relative region to get upstream from.
downstream	an integer, relative region to get downstream from
zeroPosition	an integer DEFAULT (upstream), what is the center point? Like leaders and cds combination, then 0 is the TIS and -1 is last base in leader. NOTE!: if windows have different widths, this will be ignored.
returnCoverage	logical, default: FALSE, return coverage, if FALSE returns plot instead.
acceptedLengths	an integer vector (NULL), the read lengths accepted. Default NULL, means all lengths accepted.
legendPos	a character, Default "right". Where should the fill legend be ? ("top", "bottom", "right", "left")
colors	character vector, default: "default", this gives you: c("white", "yellow2", "yellow3", "lightblue", "blue", "navy"), do "high" for more high contrasts, or specify your own colors.
addFracPlot	Add margin histogram plot on top of heatmap with fractions per positions
location	a character, default "start site", will make xlabel of heatmap be Position relative to "start site" or alternative given.
shifting	a character, default NULL (no shifting), can also be either of c("5prime", "3prime")
skip.last	skip top(highest) read length, default FALSE
title	a character, default NULL (no title), what is the top title of plot?

Value

ggplot2 grob (default), data.table (if returnCoverage is TRUE)
