I'm trying to reproduce the 3rd graph on the page of this site: http://learnr.wordpress.com/2009/03/17/ggplot2-barplots/ . However, the data below produces a ggplot with the stacks sorted in alphabetical order from the bottom up. I'd like the stacks to be in the order "Europe", "Asia", "Americas, "Africa", "Oceania". Is there an easy way to manipulate ggplot or geom_bar to do this?
library(ggplot2)
df <- structure(c(106487, 495681, 1597442,

Hi:
levels(df.m2$Region)
[1] "Africa" "Americas" "Asia" "Europe" "Oceania"
Reorder your Region factor to the following:
df.m2$Region <- factor(df.m2$Region, levels = c('Europe', 'Asia',
'Americas', 'Africa', 'Oceania'))
Then recopy the code from the definition of a onward and you should
get what you want. Worked for me.

Change the order of the levels in a factor variable:

[1] "Africa" "Americas" "Asia" "Europe" "Oceania"

My efforts to replicate your code founded on the fact that your
rename() operation seemed to have the wrong targets (or perhaps it is
from a package you did not tell us about. (I did load rehape2.
