[Rcpp-devel] [ExternalEmail] Newbie question: RInside from within a Inline/Rcpp cxxfunction

[Dan.Pagendam at csiro.au]

Apologies, in the previous email I meant to say:

 "Is it possible for me to have my cxxfunction instantiate an object of class RInside within the C++ code?"

NOT

"Is it possible for me to have my cxxfunction instantiate an object of class RInline within the C++ code?"

Hi,

this is my first post here.  I've just started to explore the uses of Rcpp, Inline and RInside and must say that I think these are really fantastic tools, which I hope to use routinely in the future.

I'm about to embark on writing some code, but before I do, I was hoping somebody can offer a quick "sanity check" for me and let me know if what I am proposing is achievable and sensible.

Bascially, I would like to write a cxxfunction in R using Rcpp and Inline so that I can execute my C++ code easily from within R.  However, I'd like my C++ code comprising the cxxfunction to make use of the R language too.  Is it possible for me to have my cxxfunction instantiate an object of class RInline within the C++ code?  I guess what I'm getting at is, can I get R to call on a C++ function which in turn calls upon R code?

I've looked at plenty of examples of code that use RInline and it seems that they are all just based around calling on R from with C++.  This is making me wonder if what I am suggesting above is either plain dumb or just not possible.

Thanks in advance for your help,

Dan
