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 signature 'SpatRaster'
datatype(x, bylyr=TRUE)

## S4 method for signature '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
