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 SpatRaster
datatype(x, bylyr=TRUE)
# S4 method for SpatVector
datatype(x)
Value
character
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)
