Arrange Gviz plotTracks() figure and basic R plot on a canvas

Last seen 3.2 years ago


I am trying to put Gviz output and a basic R plot on the same canvas.

The figures I have:

1) A basic R plot recorded with recordPlot()

2) A bunch of Gviz tracks

Attempts I took:

I tried to grab the Gviz output using grid::grid.grabExp() and use cowplot::plot_grid() to put them on the same canvas.

tp <- grid.grabExpr(plotTracks(list(gtrack,ht),from = chrstart, to=chrend, chromosome = chrm, add = TRUE))

# >Warning message:

# >In grabDL(warn, wrap, ...) :

# >one of more grobs overwritten (grab WILL not be faithful; try 'wrap = TRUE')

figure <- plot_grid(basic_R, tp)

The final figure did no 100% replicate what I saw with plotTracks(). Some (NOT ALL!) data tracks in "polygon" style lost their color fill in mountains. I could still see the colored line but the fill between colored peaks and baseline was totally lost.

Adding the 'wrap = TRUE' would not solve this problem and the error still occured.

How could I properly arrange them on the same canvas?

Thank you so much for your help!
