Combine ggplot track plots into an aligned grid. Uses patchwork to perform the alignment

Usage

draw_trackplot_grid(
  ...,
  labels,
  title = NULL,
  heights = rep(1, length(plots)),
  label_width = 0.2,
  label_style = list(fontface = "bold", size = 4)
)

Arguments

...: Plots in order from top to bottom, generally plain ggplots. To better accomodate many bulk tracks, patchwork objects which contain multiple tracks are also accepted. In this case, plot labels will be drawn from the attribute $patchwork$labels if present, rather than the labels argument.
labels: Text labels to display for each track
title: Text for overarching title of the plot
heights: Relative heights for each component plot. It is suggested to use 1 as standard height of a pseudobulk track.
label_width: Fraction of width that should be used for labels relative to the main track area
label_style: Arguments to pass to geom_text to adjust label text style

Value

A plot object with aligned genome plots. Each aligned row has the text label, y-axis, and plot body. The relative height of each row is given by heights. A shared title and x-axis are put at the top.
