#Create a new raster and set all its values to unity.
r <- raster(nrows=18, ncols=36)
r <- setValues(r,rep(1,ncell(r)))

#Create TransitionLayer objects
tr1 <- transition(r,mean,4)
tr2 <- tr1

#Extracting and replacing
tr1[cbind(1:9,1:9)] <- tr2[cbind(1:9,1:9)]
tr1[1:9,1:9] <- tr2[1:9,1:9]
tr1[1:5,1:5]
