Strange space on grid.arrange plot
I am trying to add footnote to grid.arrange graph. I presented my idea in this reproducible example: )
library(ggplot2)
library(gridExtra)
library(grid)
library(gtable)
summary(anscombe)
p1 <- ggplot(anscombe) + geom_point(aes(x1, y1), color = "darkorange", size = 3) + theme_bw()
p2 <- ggplot(anscombe) + geom_point(aes(x2, y2), color = "darkorange", size = 3) + theme_bw()
p3 <- ggplot(anscombe) + geom_point(aes(x3, y3), color = "darkorange", size = 3) + theme_bw()
p4 <- ggplot(anscombe) + geom_point(aes(x4, y4), color = "darkorange", size = 3) + theme_bw()
title <- textGrob("Some title",
gp=gpar(fontsize=20,fontface=2))
source1<- textGrob("Source: https://rpubs.com/neilfws/91339",
hjust=0,x=0,y=1,
gp=gpar(fontsize=10,fontface=3))
grid.arrange(arrangeGrob(p1,p2,p3,p4, ncol=2, sub = source1), top = title)
This code generates that picture:
with huge space below the graphs. How to get rid off of that? Why is it created?
Try using bottom instead of sub :
grid.arrange(arrangeGrob(p1,p2,p3,p4, ncol=2, bottom = source1), top = title)
One easy way is to use this code:
grid.arrange(arrangeGrob(p1,p2,p3,p4, ncol=2, sub = source1), top = title, heights = c(50,-15))
And modify the heights until you have the deserved spacing. I achieved this only setting that parameter with showed values:
