[R] Writing 'domain specific languages' with R

[Roberto Brunelli]

I would like to port to R the IPAT-S language, kind of a 'domain
specific' scripting language for developing quantitative models for
medium and long-term sustainability scenarios (www.ipat-s.org).

I think that in order to replicate its syntax I need some kind of
'macro' functionality to reparse it into R constructs. Are there any
examples of tweaking R to support a domain specific input syntax?

Thanks a lot,
