names(x)

## S4 replacement method for signature 'SpatRaster'
names(x)<-value

## S4 method for signature 'SpatRasterDataset'
names(x)

## S4 replacement method for signature 'SpatRasterDataset'
names(x)<-value

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

## S4 replacement method for signature 'SpatVector'
names(x)<-value

Arguments

x	SpatRaster, SpatRasterDataset, or SpatVector
value	character (vector)

Value

character

Note

terra enforces neither unique nor valid names. See make.unique to create unique names and {make.names} to make syntactically valid names.

Examples

s <- rast(ncols=5, nrows=5, nlyrs=3)
nlyr(s)
names(s)
names(s) <- c("a", "b", "c")
names(s)

# SpatVector names
f <- system.file("ex/lux.shp", package="terra")
v <- vect(f)
names(v)
names(v) <- paste0(substr(names(v), 1, 2), "_", 1:ncol(v))
names(v)
