Examples

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

#Create a Transition object from the raster
tr <- transition(raster,mean,4)

trS <- stack(tr, tr*2)

#Apply a Summary method
trSum <- sum(trS)

#plot(raster(trMean))
