JuliaCall: Seamless Integration Between R and Julia.

Description

JuliaCall provides you with functions to call Julia functions and to use Julia packages as easy as possible.

Examples

if (identical(Sys.getenv("AUTO_JULIA_INSTALL"), "true")) { ## The examples are quite time consuming

  ## Do initiation for JuliaCall and automatic installation if necessary

  julia <- julia_setup(installJulia = TRUE)

  ## Different ways for calculating `sqrt(2)`

  # julia$command("a = sqrt(2)"); julia$eval("a")
  julia_command("a = sqrt(2)"); julia_eval("a")

  # julia$eval("sqrt(2)")
  julia_eval("sqrt(2)")

  # julia$call("sqrt", 2)
  julia_call("sqrt", 2)

  # julia$eval("sqrt")(2)
  julia_eval("sqrt")(2)

  ## You can use `julia_exists` as `exists` in R to test
  ## whether a function or name exists in Julia or not

  # julia$exists("sqrt")
  julia_exists("sqrt")

  ## You can use `julia$help` to get help for Julia functions

  # julia$help("sqrt")
  julia_help("sqrt")

  ## You can install and use Julia packages through JuliaCall

  # julia$install_package("Optim")
  julia_install_package("Optim")

  # julia$install_package_if_needed("Optim")
  julia_install_package_if_needed("Optim")

  # julia$installed_package("Optim")
  julia_installed_package("Optim")

  # julia$library("Optim")
  julia_library("Optim")
}
