addLayer: Add or drop a layer

In raster: Geographic Data Analysis and Modeling

Description

Add a layer to a Raster* object or drop a layer from a RasterStack or RasterBrick. The object returned is always a RasterStack (unless nothing to add or drop was provided, in which case the original object is returned).

Usage

addLayer(x, ...) 
dropLayer(x, i, ...) 

Arguments

x	Raster* object
i	integer. Indices of the layers to be dropped
...	Additional arguments. The layers to add for addLayer. None implemented for dropLayer)

Value

RasterStack

subset

Examples

file <- system.file("external/test.grd", package="raster")
s <- stack(file, file, file)
r <- raster(file)
s <- addLayer(s, r/2, r*2)
s
s <- dropLayer(s, c(3, 5))
nlayers(s)
