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)

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.
