Install, update, or remove Julia environment

Source: R/julia_setup.R
install_julia_env.Rd

Instantiate the Julia environment for sdbuildR to run stock-and-flow models using Julia. For more guidance, please see this vignette.

Usage

install_julia_env(remove = FALSE)

Arguments

remove

If TRUE, remove Julia environment for sdbuildR. This will delete the Manifest.toml file, as well as the SystemDynamicsBuildR.jl package. All other Julia packages remain untouched.

Value

Invisibly returns NULL after instantiating the Julia environment.

Details

install_julia_env() will:

  • Start a Julia session

  • Activate a Julia environment using sdbuildR's Project.toml

  • Install SystemDynamicsBuildR.jl from GitHub (https://github.com/KCEvers/SystemDynamicsBuildR.jl)

  • Install all other required Julia packages

  • Create Manifest.toml

  • Precompile packages for faster subsequent loading

  • Stop the Julia session

Note that this may take 10-25 minutes the first time as Julia downloads and compiles packages.
