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.
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
# \donttest{
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))
