I have noticed that scales returned by scale_fill_brewer(type='seq')
are not always sequential and in general vary a lot between
invocations. The code below will result in different scales when
executed multiple times.

library(ggplot2)
d <- factor(floor(rnorm(50,mean=5)))
qplot
(x=c('foo','bar'),geom="histogram",stat="bin",fill=d,position='stack') +
scale_fill_brewer(type="seq", palette=1,
name="foo",
breaks=rev(c(1,2,3,4,5)),
labels=rev(c("1","2","3","4","5"))
)

This only happened recently - so does scale_fill_brewer depend on the
online service? What could I use as a workaround to end up with
identical scales?

Hi Christian,

This is related to the bug that others have reported with rearranged
categorical order on the x axis. It will be fixed in the next
version, which I'm trying to release asap.
