c {terra}

R Documentation

Combine SpatRaster or SpatVector objects

Description

With c you can:

– Combine SpatRaster objects. They must have the same extent and resolution. However, if x is empty (has no cell values), its geometry is ignored with a warning. Two empty SpatRasters with the same geometry can also be combined (to get a summed number of layers). Also see add<-

– Add a SpatRaster to a SpatRasterDataset

– Add SpatVector objects to a new or existing SpatVectorCollection

To append SpatVectors, use rbind.

Usage

## S4 method for signature 'SpatRaster'
c(x, ..., warn=TRUE)

## S4 method for signature 'SpatRasterDataset'
c(x, ...)

## S4 method for signature 'SpatVector'
c(x, ...)

## S4 method for signature 'SpatVectorCollection'
c(x, ...)

Arguments

x	SpatRaster, SpatVector, SpatRasterDataset or SpatVectorCollection
warn	logical. If TRUE, a warning is emitted if x is an empty SpatRaster
...	as for x (you can only combine raster with raster data and vector with vector data)

Value

Same class as x

Examples

r <- rast(nrows=5, ncols=9)
values(r) <- 1:ncell(r)
x <- c(r, r*2, r*3)
