[R] ggplot2: problem with large fonts and overlapping labels

[Paul Emberson]

Hi Thierry,

Thanks for your reply.  I use the pdf graphics device.  I did not know 
about the pointsize option so I will take a look.  Here is an example of 
what I might do.

pdf(onefile=FALSE, width=10, height=7)
ggplot(mtcars, aes(x=wt, y=mpg)) + geom_point() + theme_bw
grid.gedit(gPath("labels", "label"), gp=gpar(col=rgb(0,0,0), cex=1.25))
grid.gedit(gPath("xlabel"), gp=gpar(cex=1.25))
grid.gedit(gPath("ylabel"), gp=gpar(cex=1.25))
dev.off()

On this example it actually looks ok, but on my real data I have longer 
axis labels which overlap with the tick labels.

Regards,

Paul
