In terra: Spatial Data Analysis

Compare two SpatRaster, SpatVector or SpatExtent objects for equality

Description

When, comparing two SpatRasters for equality, first the attributes of the objects are compared. If these are the same, a the raster cells are compared as well. This can be time consuming, and you may prefer to use a sample instead with all.equal

Usage

## S4 method for signature 'SpatRaster,SpatRaster'
identical(x, y)

## S4 method for signature 'SpatVector,SpatVector'
identical(x, y)

## S4 method for signature 'SpatExtent,SpatExtent'
identical(x, y)

Arguments

x	SpatRaster, SpatVector, or SpatExtent
y	object of the same class as x

Value

single logical value

See Also

all.equal, compareGeom

Examples

x <- sqrt(1:100)
mat <- matrix(x, 10, 10)
r1 <- rast(nrows=10, ncols=10, xmin=0, vals = x)
r2 <- rast(nrows=10, ncols=10, xmin=0, vals = t(mat))

identical(r1, r2)
identical(r1, r1*1)
identical(rast(r1), rast(r2))
