Julia engine in knitr in progress

[Changcheng Li]

Hi,

I'm currently making an R package JuliaCall which embeds julia in R. And I have some attempts in making a julia engine for knitr using JuliaCall.

This is what it currently looks like: 

<https://non-contradiction.github.io/JuliaCall/articles/JuliaCall_in_RMarkdown.html>.

It's not perfect at now. For example, when I get a png plot in julia, I get its raw data and use things like `cat(rmarkdown::html_notebook_output_img(bytes = x, format = 'png'))` to output it in the rmarkdown document. It only works for html output imperfectly, right? I wonder what is the correct way in including plots not generated from R code in RMarkdown file generally. Should I use things like `knitr::hook_plot_md`?

Best,

Changcheng

This looks interesting! I can work with you to polish it up, but you will need to wait for two weeks before I'll have some free time. Thanks!
