Align multiple plots in ggplot2 when some have legends and others don't

Question

I have used the method indicated here to align graphs sharing the same abscissa.

But I can\'t make it work when some of my graphs have a legend and others don\'t.

Answer 1

The patchwork package by Thomas Lin Pedersen does this all automagically:

library(patchwork)
g1 + g2 + plot_layout(ncol = 1)

Can hardly get any easier than that.
