deepcopy: Deep copy

In terra: Spatial Data Analysis

Deep copy

Description

Make a deep copy of a SpatRaster or SpatVector. This is occasionally useful when wanting to use a replacement function in a shallow copy. That is a copy that was created like this: x <- y. If you use a replacement function to change an object, its shallow copies also change.

Usage

## S4 method for signature 'SpatRaster'
deepcopy(x)

## S4 method for signature 'SpatVector'
deepcopy(x)

Arguments

x	SpatRaster or SpatVector

Value

Same as x

Examples

r <- rast(ncols=10, nrows=10, nl=3)
tm <- as.Date("2001-05-03") + 1:3
time(r) <- tm
time(r)
x <- r
time(x) <- tm + 365
time(x)
time(r)

y <- deepcopy(r)
time(y) <- tm - 365
time(y)
time(r)

# or make a new object like this
z <- rast(r)
time(z) <- tm
time(z)
time(r)
