names(x)<-value

# S4 method for SpatRasterDataset
names(x)

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

# S4 method for SpatVector
names(x)

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

Arguments

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)
#> [1] 3
names(s)
#> [1] "lyr.1" "lyr.2" "lyr.3"
names(s) <- c("a", "b", "c")
names(s)
#> [1] "a" "b" "c"

# SpatVector names
f <- system.file("ex/lux.shp", package="terra")
v <- vect(f)
names(v)
#> [1] "ID_1"   "NAME_1" "ID_2"   "NAME_2" "AREA"   "POP"   
names(v) <- paste0(substr(names(v), 1, 2), "_", 1:ncol(v))
names(v)
#> [1] "ID_1" "NA_2" "ID_3" "NA_4" "AR_5" "PO_6"
