c: 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 or SpatRasterCollection

-- Add SpatVector objects to a new or existing SpatVectorCollection

To append SpatVectors, use rbind.

Usage

# S4 method for SpatRaster
c(x, ..., warn=TRUE)
# S4 method for SpatRasterDataset
c(x, ...)
# S4 method for SpatRasterCollection
c(x, ...)
# S4 method for SpatVector
c(x, ...)
# S4 method for SpatVectorCollection
c(x, ...)

Value

Same class as 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)

Examples

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