R help - Dec 2009 - ggplot: Problem with legend background

Dear R-users,

I am preparing graphs for an upcoming article using the different functions
of the ggplot2 package and I've been having problems with the legend
background. It doesn't seem to scale when the text size is increased.
Here's
the mandatory reproducible example:

library(ggplot2)
repFrame <- data.frame(A= 1:10, B= rnorm(1:10), groupNum = rep(c("First
group", "Second group"),each=5))
testPlot <- ggplot(repFrame, aes(x=A, y = B, group = groupNum)) +
opts(legend.position=c(0.85,0.3), legend.background
theme_rect(fill="white"), legend.text=theme_text(size=16),
legend.title=theme_text(size=20))
testPlot + geom_point(aes(colour= groupNum))

As you can see, the text doesn't fit in the white rectangle. I suspect there
is a theme setting I could modify to fix this, but I can't seem to find
which one.

I sincerely thank you for your time and assistance.

Luc

Hi Luc,

You want:

legend.title=theme_text(size=20, hjust = 0)

So the legend title is left aligned, not centred.
