Dear All,
I want to do regression kriging and cokriging with the following datasets: a
point data set, DEM, EVI, landcover map, TWI, TRI and soil map. All these maps
are spatialgriddataframes and have the same extend. The landcover map has 9
classes.
Question1.
How can i remove the ninth class in R because it does not have to be included
in
geostatical analysis.
Question 2
how can i use the map created in Q1 to clip the other 5 aboventioned maps (eg
DEM etc) or how can i create a mask from the map in Q1.
Please find the summary of landcover:
