[TxMt] R, Sweave, markdown

[Hans-Jörg Bibiko]

In principal it won't be such a big deal to write such a parser. But  
the problems will appear in the details. One has to create a kind of  
meta syntax - processing statements - for all these R chunks. E.g.

@RCODE quiet@
a <- matrix(c(1,2,3,4,5,6), nrow=2 byrow=T)
@/RCODE@

foo foo

@RCODE insertAsTable noCommandLine@
print(a*2)
@/RCODE@

etc.

But this would be mean to reinvent the wheel twice in some sense.  
Markdown to LaText and Sweave for LaTeX works fine.

On the other hand I use quite often the R bundle command 'Execute  
Selection/Document in R and' > 'Insert Result' for such things.

Of course, to have such a pre-parser for expanding R code chunks and  
insert the result depending on the current language (HTML, LaTeX,  
Markdown, Plain Text) would be nice.
