Compare two SpatRaster, SpatVector or SpatExtent objects for equality

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

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

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

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

Arguments

x

SpatRaster, SpatVector, or SpatExtent

y

object of the same class as x

Value

single logical value

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)
#> [1] TRUE
identical(r1, r1*1)
#> [1] TRUE
identical(rast(r1), rast(r2))
#> [1] TRUE
