It's not entirely clear to me how you expect the values to be
calculated, but you might look at partial dependence plots, for
example as implemented in the pdp package.

Dear List,
I hope this finds you well. Please I have done a Land cover classification
using randomForest. I used selected satellite image bands as input
variables. I have four thematic classes. I obtained the general variable
importance using *varImpPlot (my model) . *Now I want to have bar chart
plot showing each thematic class and the variable importance for each
class. That is, how each band is ranked in predicting a thematic class. I
tried using this function:
*importance = varImp(my model, scale= TRUE)*
*plot (importance. *
However it did not work. I tried to put in *geom= "bar*". And I had error.
Please I will be glad to get some assistance.
Thank you.
Best regards,
Enoch
