This doesn't appear to work with a checkout of the latest ggplot2 from github. When I plot, I get "Error: Don't know how to add o to a plot". If I remove this from my R script, plotting succeeds.

This does not work with ggplot2 version 0.9.2.1 (the theme_xxx have been deprecated and theme_segment was not replaced with element_segment). I changed all the other theme_xxx's but I am not sure how to replace theme_segment. Any help would be great!

theme_segment has been replaced with element_line.
