Set up Julia environment for sdbuildR — use

Create Julia environment to simulate stock-and-flow models. use_julia() looks for a Julia installation, and will install Julia as well as some required packages if not found. Keep in mind that the installation can take around 5-15 minutes. In every R session, use_julia() needs to be run once, which can take around 20 seconds.

Usage

use_julia(
  stop = FALSE,
  version = "latest",
  JULIA_HOME = NULL,
  dir = NULL,
  force = FALSE,
  force_install = FALSE,
  ...
)

Arguments

stop: If TRUE, stop active Julia session. Defaults to FALSE.
version: Julia version. Default is "latest", which will install the most recent stable release.
JULIA_HOME: Path to Julia installation. Defaults to NULL to locate Julia automatically.
dir: Directory to install Julia. Defaults to NULL to use default location.
force: If TRUE, force Julia setup to execute again.
force_install: If TRUE, force Julia installation even if existing version is found. Defaults to FALSE.
...: Optional arguments passed to JuliaCall::julia_setup()
