CombineTracks {Signac}

Combine genome region plots

Description

This can be used to combine coverage plots, peak region plots, gene annotation plots, and linked element plots. The different tracks are stacked on top of each other and the x-axis combined.

Usage

CombineTracks(plotlist, expression.plot = NULL, heights = NULL, widths = NULL)

Arguments

plotlist

A list of plots to combine. Must be from the same genomic region.

expression.plot

Plot containing gene expression information. If supplied, this will be placed to the left of the coverage tracks and aligned with each track

heights

Relative heights for each plot. If NULL, the first plot will be 8x the height of the other tracks.

widths

Relative widths for each plot. Only required if adding a gene expression panel. If NULL, main plots will be 8x the width of the gene expression panel

Value

Returns a patchworked ggplot2 object

Examples

p1 <- PeakPlot(atac_small, region = "chr1-29554-39554")
p2 <- AnnotationPlot(atac_small, region = "chr1-29554-39554")
CombineTracks(plotlist = list(p1, p2), heights = c(1, 1))
