Patchwork does not collect guides with code in documentation… the reprex code is following:
Does anyone know what is causing the issue here, please?
library(ggplot2)
#> Warning: package 'ggplot2' was built under R version 4.0.5
library(patchwork)
p1a <- ggplot(mtcars) +
geom_point(aes(mpg, disp, colour = mpg, size = wt)) +
ggtitle('Plot 1a')
p2 <- ggplot(mtcars) +
geom_boxplot(aes(gear, disp, group = gear)) +
ggtitle('Plot 2')
p3 <- ggplot(mtcars) +
geom_point(aes(hp, wt, colour = mpg)) +
ggtitle('Plot 3')
p1a | (p2 / p3) + plot_layout(guides = 'collect')

Session info – patchwork is updated
>Solution :
(p1a | (p2 / p3)) + plot_layout(guides = 'collect')
Without the parentheses, the plot_layout() will only relate to the immediately preceding term, (p2 / p3). From the documentation for plot_layout():
If you are nesting grids, the layout is scoped to the current nesting
level.
I think in this case "the current nesting level" will be the most recent term.
