plotReads: Plot compact representation of read counts on a chromosome

Description

Creates an image of all read counts for a chromosome.

Usage

.plotReads(x, scale = c("total", "ratio"), log = TRUE, ...)

Arguments

x
A two column matrix with read counts (as produced by strandPileup).
scale
Character string indicating whether to plot the total number of reads on both strands or the ratio between them.
log
Logical indicating whether to use log read counts.
...
Further plotting arguments.

Value

Called for its side effect.

Details

The read counts (or read count ratios) are plotted as a Hilbert curve using hilbertImage.
