Data type of a SpatRaster or SpatVector

Get the data types of the fields (attributes, variables) of a SpatVector or of the file(s) associated with a SpatRaster. A (layer of a) SpatRaster has no datatype if it has no values, or if the values are in memory.

Usage

# S4 method for class 'SpatRaster'
datatype(x, bylyr=TRUE)

# S4 method for class 'SpatVector'
datatype(x)

Arguments

x

SpatRaster or SpatVector

bylyr

logical. If TRUE a value is returned for each layer. Otherwise, a value is returned for each data source (such as a file)

Value

character

Examples

f <- system.file("ex/lux.shp", package="terra")
v <- vect(f)
datatype(v)
#> [1] "double" "string" "double" "string" "double" "long"  

f <- system.file("ex/elev.tif", package="terra")
r <- rast(f)
datatype(r)
#> [1] "INT2S"

# no data type
datatype(rast()) 
#> [1] ""
