[R-sig-Geo] stplot - legend/classes of categorical vairable

[Aurelie C.Godin]

I'm getting strange behavior in the bar legend with factors ...
I cut my data into intervals and plotted results using stplot, however now
the levels are not appearing in the same order as levels(factor)...?

For example, I get the same problem here:
library(spacetime)
example(STFDF)
set.seed(42) 
gridded(stfdf at sp) = TRUE 
stfdf$f = factor(sample(c("a", "b", "c"), 12, replace = TRUE))
levels(stfdf$f)
levels(stfdf$f)<-c('0','(0,5]','(5,25]')
levels(stfdf$f)
library(RColorBrewer)
stplot(stfdf[,,"f"], col.regions = brewer.pal(3, "Accent")) 

Thoughts on how to fix this?
