call: Call julia functions.

In JuliaCall: Seamless Integration Between R and 'Julia'

Call julia functions.

Description

julia_do.call is the do.call for julia. And julia_call calls julia functions. For usage of these functions, see documentation of arguments and examples.

Usage

julia_do.call(
  func_name,
  arg_list,
  need_return = c("R", "Julia", "None"),
  show_value = FALSE
)

julia_call(
  func_name,
  ...,
  need_return = c("R", "Julia", "None"),
  show_value = FALSE
)

Arguments

func_name	the name of julia function you want to call. If you add "." after 'func_name', the julia function call will be broadcasted.
arg_list	the list of the arguments you want to pass to the julia function.
need_return	whether you want julia to return value as an R object, a wrapper for julia object or no return. The value of need_return could be TRUE (equal to option "R") or FALSE (equal to option "None"), or one of the options "R", "Julia" and "None".
show_value	whether to invoke the julia display system or not.
...	the arguments you want to pass to the julia function.

Details

Note that named arguments will be discarded if the call uses dot notation, for example, "sqrt.".

Examples

if (identical(Sys.getenv("AUTO_JULIA_INSTALL"), "true")) { ## julia_setup is quite time consuming
  ## doing initialization and automatic installation of Julia if necessary
  julia_setup(installJulia = TRUE)
  julia_do.call("sqrt", list(2))
  julia_call("sqrt", 2)
  julia_call("sqrt.", 1:10)
}
