Re: [R] Arranging ggplot2 objects with ggplotGrob()

Rui Barradas Fri, 24 Jul 2020 14:57:29 -0700

Hello,

I've just tried it.


library(ggplot2)
#library(grid)
library(cowplot)

s <- ggplot(data = subset(iris, Species == 'virginica'),aes(Sepal.Length, Sepal.Width)) + geom_point()v <- ggplot(data = subset(iris, Species == 'setosa'), aes(Sepal.Length,Sepal.Width)) + geom_point()


#g2 <- ggplotGrob(s)
#g3 <- ggplotGrob(v)
#g <- rbind(g2, g3, size = "first")

cowplot::plot_grid(s, v, align = "h", nrow = 2, rel_heights = 2:1)


Hope this helps,

Rui Barradas

Sigh, we know the code works but we do not know what the plots are

and we cannot play around with them to see if we can help you if we
have nothing to work with.

     So this is not possible without using one of those two packages?

I got the impression I should be able to use grid.arrange to do so but
was not able to get it to work without disturbing the width alignment
above...

No need to play around with anything. I am simply looking for
assistance on how to use eg arrangeGrob to not only align two plots
columnwise but also adjust their heights relative to each other rather
than 1:1.

Can arrangeGrob() be used for that?

Look at https://cran.r-project.org/web/packages/egg/vignettes/Ecosystem.html 
where there are two mpg charts, one above the other. What would I need to add 
to:

|library(gtable) g2 <-ggplotGrob(p2) g3 <-ggplotGrob(p3) g <-rbind(g2, g3, size = 
"first") g$widths <-unit.pmax(g2$widths, g3$widths) grid.newpage() grid.draw(g) |

|to make the second chart 1/2 the size of the top one?|
