This function allows you to you to add arrows representing genes to an R wiggle plot. Written by Tovah Markowitz.
plot_gene_arrow(geneEnd, geneLength, orientation, minima = 400, color = "black", height = 0.2, yPos = -1)
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. |
