coverageplot {chipseq} | R Documentation

## 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

`peaks1, peaks2` | A set of peaks as described by ranges over a coverage vector.
`i` | Which peak to use.
`xlab, ylab` | Axis labels.
`opposite` | Logical specifying whether the two peaks should be plotted on opposite sides (appropriate for positive and negative strand peaks).
`...` | extra arguments.

### 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")
