描述
Summary
When setting hjust to a value outside 0..1 range, in cases it would push text over the plotting area edge, text overlaps point. The problem can be reproduced only at certain plotting area sizes, rather small ones in most cases. (Anyway, it seems like setting hjust reduces repulsive force in the y direction.)
(@slowkow @AliciaSchep While adding visual test cases I noticed some problems, this is one of them.)
Minimal code example
Here is the minimum amount of code neeeded to demonstrate the issue:
dat <- subset(mtcars, wt > 2.75 & wt < 3.45)
dat$car <- rownames(dat)
set.seed(42)
p <- ggplot(dat, aes(wt, mpg, label = car)) +
geom_point()
Problem on right edge.
p + geom_text_repel(hjust = -0.5)
Problem on bottom edge.
p + geom_text_repel(vjust = 1.5, angle = 90)
Problem on left edge.
p + geom_text_repel(hjust = 1.5)
Here is an image of the output produced by the code immediately above.

Suggestions
None, as I haven't studied the repulsion code.
