The following summary methods are available: mean, Median, max, min, range, prod, sum, any, all
# S4 method for TransitionStack Summary(x, ..., na.rm = FALSE)
further arguments passes to or from methods
logical, should missing values be removed?
These methods compute a summary statistic based on cell values of layers in a TransitionStack. The result of these methods is always a single TransitionLayer.
#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))
