julia_setup does the initial setup for the JuliaCall package.
It setups automatic type conversion, Julia display systems, etc,
and is necessary for every new R session to use the package.
If not carried out manually, it will be invoked automatically before other julia_xxx functions.
julia_setup(JULIA_HOME = NULL, verbose = TRUE, install = TRUE, force = FALSE, useRCall = TRUE, rebuild = FALSE)
| JULIA_HOME | the file folder which contains julia binary, if not set, JuliaCall will look at the global option JULIA_HOME, if the global option is not set, JuliaCall will then look at the environmental variable JULIA_HOME, if still not found, JuliaCall will try to use the julia in path. |
|---|---|
| verbose | whether to print out detailed information
about |
| install | whether to execute installation script for dependent julia packages, whose default value is TRUE; but can be set to FALSE to save startup time when no installation of dependent julia packages is needed. |
| force | whether to force julia_setup to execute again. |
| useRCall | whether or not you want to use RCall.jl in julia, which is an amazing package to access R in julia. |
| rebuild | whether to rebuild RCall.jl, whose default value is FALSE to save startup time. If a new version of R is used, then this parameter needs to be set to TRUE. |
The julia interface, which is an environment with the necessary methods like command, source and things like that to communicate with julia.
## julia_setup is quite time consuming julia <- julia_setup()
