juliaFun {JuliaConnectoR}

Wrap a Julia function in an R function

Description

Creates an R function that will call the Julia function with the given name when it is called. Like any R function, the returned function can also be passed as a function argument to Julia functions.

Usage

juliaFun(name, ...)

Arguments

name

the name of the Julia function

...

optional arguments for currying: The resulting function will be called using these arguments.

Examples

if (juliaSetupOk()) {

   # Wrap a Julia function and use it
   juliaSqrt <- juliaFun("sqrt")
   juliaSqrt(2)
   # In the following call, the sqrt function is called without
   # a callback to R because the linked function object is used.
   juliaCall("map", juliaSqrt, c(1,4,9))

   # may also be used with arguments
   plus1 <- juliaFun("+", 1)
   plus1(2)
   # Results in an R callback (calling Julia again)
   # because there is no linked function object in Julia.
   juliaCall("map", plus1, c(1,2,3))
