Description

Function for reclassifying grid files to get a combined statification from more than one grid

Usage

ecospat.rcls.grd(in_grid,no.classes)

Value

Returns a reclassified Raster object

Arguments

in_grid

The grid to be reclassified.

no.classes

The number of desired new classes.

Author

Details

This function reclassifies the input grid into a number of new classes that the user defines. The boundaries of each class are decided automatically by splitting the range of values of the input grid into the user defined number of classes.

Examples

library(raster)
library(classInt)

bio3<- raster(system.file("external/bioclim/current/bio3.grd",package="biomod2"))
bio12<- raster(system.file("external/bioclim/current/bio12.grd",package="biomod2"))

B3.rcl<-ecospat.rcls.grd(bio3,9) 
B12.rcl<-ecospat.rcls.grd(bio12,9)
B3B12.comb <- B12.rcl+B3.rcl*10

# Plotting a histogram of the classes
hist(B3B12.comb,breaks=100,col=heat.colors(88)) 
# Plotting the new RasterLayer (9x9 classes)
plot(B3B12.comb,col=rev(rainbow(88)),main="Stratified map")
