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

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.

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.

Examples

if (FALSE) {
library(rgee)
ee_Initialize()

# Earth Engine List
ee_SimpleList <- ee$List$sequence(0, 12)
ee_NewList <- ee_SimpleList$map(
  ee_utils_pyfunc(
    function(x) {
      ee$Number(x)$add(x)
    }
  )
)

ee_NewList$getInfo()

# Earth Engine ImageCollection
constant1 <- ee$Image(1)
constant2 <- ee$Image(2)
ee_ic <- ee$ImageCollection(c(constant2, constant1))
ee_newic <- ee_ic$map(
  ee_utils_pyfunc(
    function(x) ee$Image(x)$add(x)
  )
)
ee_newic$mean()$getInfo()$type
}
