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
```{r}

## The examples are quite time consuming
## Do initiation for JuliaCall
julia <- julia_setup()
## 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)
JuliaObject 5
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")
