replace_values: Replace values of a SpatRaster

In terra: Spatial Data Analysis

Replace values of a SpatRaster

Description

Replace values of a SpatRaster. These are convenience functions for smaller objects only. For larger rasters see link{classify} or subst

Usage

## S4 replacement method for signature 'SpatRaster,ANY,ANY,ANY'
x[i, j, k] <- value

## S4 replacement method for signature 'SpatVector,ANY,ANY'
x[i, j] <- value

## S4 replacement method for signature 'SpatExtent,numeric,missing'
x[i, j] <- value

Arguments

x	SpatRaster
i	row numbers. numeric, logical, or missing for all rows. Can also be a SpatRaster or SpatVector
j	column numbers. numeric, logical or missing for all columns
k	layer number. numeric, logical or missing for all layers
value	numeric, matrix, or data.frame

Value

SpatRaster

Examples

## SpatRaster
r <- rast(ncols=5, nrows=5, xmin=0, xmax=5, ymin=0, ymax=5)
r[] <- 1:25
r[1,] <- 5
r[,2] <- 10
r[r>10] <- NA

## SpatVector
f <- system.file("ex/lux.shp", package="terra")
v <- vect(f)
v[2,2] <- "hello"
v[1,] <- v[10,]
v[,3] <- v[,1]
v[2, "NAME_2"] <- "terra"
head(v, 3)
