Hi,
I downloaded and ploted maps from http://gadm.org/ for Austria and a
special province:
### <CODE> ###
library(sp)
library(RColorBrewer)
# load from web
con <- url("http://gadm.org/data/rda/AUT_adm2.RData";)
print(load(con)) # gadm hold all the data!
close(con)
# select one province
noe = new("SpatialPolygonsDataFrame")
noe = gadm[gadm$NAME_1=="Nieder\xf6sterreich",]
noe$NAME_1 = factor(noe$NAME_1)
noe$NAME_2 = factor(noe$NAME_2)
# utf8
noe_bez_names = iconv(noe$NAME_2, "ISO_8859-2", "UTF-8")
noe$bez = factor(noe_bez_names)
# plot
col = rainbow(length(levels(noe$bez)))
spplot(noe, zcol="bez", col.regions=col, col="white", scales=list(draw =
TRUE), colorkey=TRUE)
### </CODE> ###
everything just works fine, but the legend (colorkey) is ordered in the
wrong direction...
How can I rearrange / sort the legend?
