ee_utils_pyfunc

Wrap an R function in a Python function with the same signature.

Description

This function could wrap an R function in a Python function with the same signature. Note that the signature of the R function must not contain esoteric Python-incompatible constructs.

Usage

ee_utils_pyfunc(f)

Arguments

`f`	An R function

Value

A Python function that calls the R function f with the same signature.

Note

py_func has been renamed to ee_utils_pyfunc just to maintain the rgee functions name's style. All recognition for this function must always be given to reticulate.
