Is it possible to publish a R Markdown from JSL

All,
Is it possible to publish a R Markdown from JSL ?

Provided the current R support functions - I don't know how to achieve that. However, has anybody explored this so far ?

Accepted answers

Your R code would look the same, so this should work provided you already installed knitr or rmarkdown:

Names default to here( 1 );

R Init();
R Submit( "\[
	library( knitr )
	
	setwd( "C:/temp" )
	
	write( "## My Markdown File
Let's add:
``` {r}
1 + 1
```
",
	"myrmarkdown.rmd"
	);
	
	knit( "myrmarkdown.rmd", output = "mymarkdown.md" )
	knit2html( "myrmarkdown.rmd", output = "mymarkdown.html" )
]\" );

Open( "C:/temp/mymarkdown.html" );

For anyone unfamiliar with what that will look like, here is the html output:

@ih,
A follow -up question - Would the format be any different to publish a Latex document ?

Every tutorial I find on Latex is guiding that the document should be a "Sweave" or a text file that is saved as a ".tex"

Is there another way about it ?

I am far from an expert here but I am certain it is possible to convert a .rmd to a .md to a .tex to a .pdf as I am pretty sure that is rmarkdown's standard workflow. The why's and hows should be in the rmarkdown documentation. If you can figure out the steps required to call pandoc_convert (page 41) that should let you save the .tex file, getting you from .rmd to .tex.

If you just want to 'publish' a .tex to .pdf I think you can skip R entirely and call MiKTeX (actually pdflatex) directly using RunProgram() in JSL. I have not tried this but it might be as simple as:

//Untested Code
RunProgram( "pdflatex.exe", options( {"mymarkdownfile.tex"} ) )

Hi,

How do you add thinks like title, author to the R Markdown as part of your example. I tried to add that in Write() section but got an error. I appeciate your help. Thanks
