generating object with multiple polygons

Karla,
You can do

library(raster)
slices <- bind(slice1, slice2)

Dear all,

This might be a newbie question, so I'd appreciate your patience with

this.

I'm obtaining climatic data from worldclim and generating polygons based

on

different climatic limits:

library(raster)
xx<-getData('worldclim', var='bio', res=10)$bio1
slice1 <- rasterToPolygons(xx, fun = function(x) {x > 200 & x < 260})
slice2 <- rasterToPolygons(xx, fun = function(x) {x > 250 & x < 300})

Now, I'd like to combine "slice1" and "slice2" into the same
"SpatialPolygonsDataFrame" object, but I do not want to merge them.

Any help will be greatly appreciated.

Karla
