For the original notebook, please go to https://nbviewer.jupyter.org/github/Non-Contradiction/JuliaCall/blob/master/example/JuliaCall_in_Jupyter_R_Notebook.ipynb.

Here I generate a markdown file from part of the notebook and include it in this vignette.

library(JuliaCall)
julia_setup()
Julia at location /Applications/Julia-0.6.app/Contents/Resources/julia/bin will be used.

It seems that you are not in the terminal. A simple julia console will be started.
Press ESC or CTRL+C to exit.

julia> sqrt(2)
1.4142135623730951 
julia> @doc sqrt
sqrt(x)

Return ${x}$. Throws DomainError for negative Real arguments. Use complex negative arguments instead. The prefix operator √ is equivalent to sqrt. 

julia> exit
