ggplot2 increase space between legend keys
How can I increase the space between the keys of the legend of ggplot2 plot?
library(ggplot2)
ggplot(aes(mpg, wt, colour = factor(cyl)),
, data = mtcars) +
geom_point() +
theme(legend.direction = "horizontal",
legend.position = "bottom") +
guides(color = guide_legend(nrow=2))
I am looking for a ggplot2 option that add a kind of vertical adjustment between (key 4 and key 6) in the plot above? Should I create a custom legend key?
PS: I want to increase the blank space between boxes not between labels.
the desired plot is :
NOTE: No the question is not duplicated of the other question. We want here to add a vertical spacing between items that are already in multiple rows. In the other question we have 1-row legend and we want to add spaces (horizontal) between items.

@Heroka no.it is not a duplicate.I don't want to change the key size. just the space between the keys. You can try the solution in the link to check this.

gridorgridExtramight help, I've never used them much though... ThegridExtravignette looks somewhat promising, but is far from giving a clear solution.

An alternative (and probably easier) solution is using legend.key and legend.key.size in the theme part of your code:

guides(color = guide_legend(nrow = 2)) +

legend.position = 'bottom',
legend.key = element_rect(size = 5),
legend.key.size = unit(1.5, 'lines'))
this gives:
In case you are calling theme_bw or theme_classic before manipulating the legend, you should set the color of the legend rectangle:
legend.key = element_rect(size = 5, color = 'white') #or: color = NA

Could you explain the difference between the size property oflegend.keyand thelinesproperty oflegend.key.size. Which one controls the spacing between the keys (i.e., the grey boxes + the label)?

@BerkU. Thesizeparameter oflegend.keydetermines the size of the boundary line. Thelinesproperty oflegend.key.sizedetermines the size of the whole box.

This did not solve my situation, because thelinesmade some legend symbols increase together with the box. In my situation, the point symbol did not increase (same as your example) but the line symbol did. As my lines were vertical, the box kept getting taller aslineswas increased, without increasing the space between the two columns of the legend. Will report back if I find a solution.

Here a solution using gtable. Basically I am extracting legend grobs table and I add a row in the legend table.
library(gtable)
library(grid)
## transform the ggplot to a grobs table
p_table <- ggplot_gtable(ggplot_build(p))
## extract legend
leg <- which(sapply(p_table$grobs, function(x) x$name) == "guide-box")
## this is the tricky part !
## add a row in the second position (pos=2)
p_table$grobs[[leg]]$grobs[[1]] <-
gtable_add_rows(p_table$grobs[[leg]]$grobs[[1]],
unit(0.5, "line"), ## you can increase the height here
pos=2) ## since I have 2 rows , I insert it in the middle
plot(p_table)
PS: I dont' know here how to coerce the table to a plot again! maybe someone else can help here ( I am just plotting it and losing the object structure)
