terra (version 1.8-80)

selectRange: Select the values of a range of layers, as specified by cell values in another SpatRaster

Description

Use a single layer SpatRaster to select cell values from different layers in a multi-layer SpatRaster. The values of the SpatRaster to select layers (y) should be whole numbers between 1 and nlyr(x) (values outside this range are ignored).

See rapp for applying a function to a range of variable size.

See extract for extraction of values by cell, point, or otherwise.

Usage

# S4 method for SpatRaster
selectRange(x, y, z=1, repint=0, filename="", ...)

Value

Examples

r <- rast(ncols=10, nrows=10)
values(r) <- 1
s <- c(r, r+2, r+5)
s <- c(s, s)
set.seed(1)
values(r) <- sample(3, ncell(r), replace=TRUE)
x <- selectRange(s, r)

x <- selectRange(s, r, 3)
