Plot coverage on a small interval.

Description

A function that plots one or two coverage vectors over a relatively small interval in the genome.

Usage

coverageplot(peaks1, peaks2 = NULL, i = 1,
             xlab = "Position", ylab = "Coverage",
             opposite = TRUE, ...)

Arguments

Author(s)

Examples

cov <- Rle(c(1:10, seq(10, 1, -2), seq(1,5,2), 4:1), rep(1:2, 11))
peaks <- slice(cov, 3)
peaks.cov <- Views(cov, ranges(peaks))
peaks.cov.rev <- rev(peaks.cov)
coverageplot(peaks.cov, peaks.cov.rev, ylab = "Example")
