R help - Aug 2008 - ggplot2: Changes to grobs not saved to file output

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.

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.

Regards,

Hadley
