How to change the spacing between the legend and the panel in ggplot2

Problema

We want to increase the spacing between the legend and the panel in ggplot2.

library(ggplot2)
xy <- data.frame(x = 1:10, y = 10:1, type = rep(LETTERS[1:2], each=5))
plot <- ggplot(data = xy) +
        geom_point(aes(x = x, y = y, colo r= type))

Solution

We use the argument legend.box.margin to add 20 points to the left.

plot <- plot + theme(legend.box.margin = margin(0, 0, 0, 20))
