[R-sig-eco] Axis color change ggplot2

[Jonathan Tonkin]

Hi Louis,

Where you have specified "e+  geom_errorbar......" you haven't assigned it
to "e" as you have elsewhere. i.e. "e <- e+  geom_errorbar" (all these e's
are slightly confusing!). So when you change the axis text to blue, you're
assigning it to the version prior to adding the error bars etc.

Hope that makes sense.
