ggplot2 : to change the title of legend

[Michel ARNAUD]

Hello
I don't arrive to change the title of the legend
My code is :
library(ggplot2)
ma <- max(General$AgeChangCat) ; mi <- min(General$AgeChangCat)
Test$Recrutement <- factor(Test$CadNonCadRecrut)
p <-
ggplot(Test, aes(x=factor(Cat1), y=AgeChangCat )) +
ylim(mi,ma) +
geom_point() +
geom_boxplot(aes(fill = Recrutement)) +
labs(title = "Age", x="catégorie", y="Age") +
theme(legend.position = c(0.1,0.9), legend.background = element_rect(colour = "black"))
p

Michel,

In order to change the legend title use:

p<- p + scale_fill_discrete(name="legendName")

In order to change the appearance of the title use:

p + theme(legend.title = element_text(colour="red", size=8, face="bold"))

I hope this helps.

David
