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.

[R] ggplot2: Changes to grobs not saved to file output
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.
