setValues: Set the values of raster cells or of geometry attributes

Description

Set cell values of a SpatRaster or the attributes of a SpatVector. For large SpatRaster objects use init instead to set values.

Usage

# S4 method for SpatRaster,ANY
values(x)<-value
# S4 method for SpatRaster,ANY
setValues(x, values)
# S4 method for SpatVector,ANY
values(x)<-value

Arguments

x

SpatRaster or SpatVector

value

For SpatRaster: matrix or numeric, the length must match the total number of cells (ncell(x) * nlyr(x)), or be a single value. For SpatVector: data.frame, matrix, vector, or NULL

values

Same as for value

Value

The same object type as x

Examples

# NOT RUN {
f <- system.file("ex/elev.tif", package="terra")
r <- rast(f)
x <- setValues(r, 1:ncell(r))
x
values(x) <- runif(ncell(x))
x
head(x)

f <- system.file("ex/lux.shp", package="terra")
v <- vect(f)
values(v) <- data.frame(ID=1:12, name=letters[1:12])
head(v)
# }
