Following the example under:
library(sp) library(automap) loadMeuse() demo(meuse) # Ordinary kriging kr = autoKrige(log(zinc)~1, meuse, meuse.grid) spplot(kr$krige_output,'var1.pred')
I get a plot with an interpolated map and a legend. The map and the legend have logarithmic vales. In many cases, a logarithmic scaled map is what I want. However, a logarithmic legend is not very useful.
How can I can keep the logarithmic color scaling and get a readable legend in R?
