Unfortunately it's not particularly easy in the current version. In
the next version, you can do:
p <- qplot(wt, mpg, data=mtcars, colour=cyl)
# Get the plot grob
grob <- ggplotGrob(p)
# Modify it place
grob <- geditGrob(grob, gPath("strip","label"), gp=gpar(fontface="bold"))
# Draw it
pdf(...)
grid.newpage()
grid.draw(grob)
dev.off()
I think in the current version you can do
qplot(wt, mpg, data=mtcars, colour=cyl)
grob <- grid.grab()
and then follow the remaining steps.

Hadley

Hello, Maybe I missed something - most likely .:-( I create a gplot and then makes some changes to the plot using grid graphics functions. These changes show up on the display OK, but when I save using ggsave() the grid changes do not show up. How do I save the plot with these changes? Thanks in advance. -- View this message in context: http://www.nabble.com/ggplot2%3A-Changes-to-grobs-not-saved-to-file-output-tp19220492p19220492.html Sent from the R help mailing list archive at Nabble.com.
