[R] ggplot rank stack bar automatically.

[Ista Zahn]

Hi vd,

The answer to the first part of your question is reorder. To continue the 
learnr example:


df.m <- transform(df.m, Period = reorder(Period, -1*value))

ggplot(df.m, aes(x = Period, y = value/1e+06, fill = Region))  +
  geom_bar(stat = "identity", position = "stack")

For the second question: please give a reproducible example.

Best,
Ista
