With geom_label instead of geom_text, my labels get a background shape with a black outline shape. I know I can control the text size with size argument, but this doesn't affect the border. Is it possible to control the thickness of this black outline border?
Like having a result similar to the plot on the right hand side:
Example:
library(tidyverse)
ggplot(rownames_to_column(mtcars, "name")) + geom_label(aes(label=name, x=mpg, y=hp), size=4)
Thanks,
The label.size parameter can be set per-layer. It is not an aesthetic in the sense that you can map data to this parameter, so splitting the thin and thick outlined text in different layers seems the only sensible option.
library(tidyverse)
ggplot(rownames_to_column(mtcars, "name")) +
geom_label(data = ~ tail(.x, -4),
aes(label=name, x=mpg, y=hp),
size=4, label.size = 0.25) +
geom_label(data = ~ head(.x, 4),
aes(label=name, x=mpg, y=hp),
size=4, label.size = 2)

The option you need is geom_label(label.size = n)
library(tidyverse)
ggplot(rownames_to_column(mtcars, "name")) +
geom_label(aes(label = name, x = mpg, y = hp),
size = 4,
label.size = 2)
