Hello all
I have a geology map that has three level, bellow
<-geology
lithology landscape landform
landform level is used as covariate (with codes=1,2,3,4,5) for training of
neural network, but this level has missing data as NA.
I want to replace the missing data of landform level with 0 (zero). Finally,
landform will have codes 0,1,2,3,4,5.
