Description

This function allows you to you to add arrows representing genes to an R wiggle plot.
Written by Tovah Markowitz.

Usage

plot_gene_arrow(geneEnd, geneLength, orientation, minima = 400,
  color = "black", height = 0.2, yPos = -1)

Arguments

geneEnd	A numeric position on the x-axis of the 3' end of the gene. No default.
geneLength	The length of the gene. No default.
orientation	A value of 1 for genes on the Watson strand or -1 for genes on the Crick strand. No default.
minima	A minimal gene length before the arrow starts turning inside out. Dependent on the range of the x-axis. Default is 400 bp.
color	Define the color of the gene. Default is black.
height	To adjust to the height of the gene bar. Default is 0.2.
yPos	To adjust the position of the gene on the y-axis. Default is -1.
