Porting Raven to R

[salbers]

Hi there,

I am curious if this model has been ported to the R programming language? Do you know of any efforts underway towards that end?

Thanks in advance!

Hi Sam

The model itself has not been ported to R and there are no plans to do so at the moment. I believe the program is currently compiled in C++ for speed of execution.

However, there is an associated R package called RavenR which you can find in the downloads page, which is currently under revision and will be updated again in the coming months. The RavenR package supports pre- and post-processing of model files, diagnostics, plots, and a few other things, although the model is still compiled and runs separately.

If you do have suggestions for compiling in R or additions to the RavenR package, please let us know! Always happy for others to get involved or offer suggestions.

Cheers,
Rob

Hi Rob,

Thanks for the response. So there is a package in R called Rcpp that calls C++ code directly from R. This maintains the speed of c++ but leverages the readability and popularity of R. Where does the code for raven live? Is it on github? I'd be interested in having a crack at porting it to R but obviously we need to see the c++ code.

Again thanks for the response.

Hi Sam

The source code is also available for download directly on the Raven Downloads page (http://www.civil.uwaterloo.ca/jrcraig/Raven/Downloads.html) for the latest version 2.7, which should be a good chance to try out the Rcpp package. The development version is on CHyMS, I would recommend you contact Dr. Craig (jrcraig@uwaterloo.ca) if you are interested in becoming more involved in the program in general.

Let me know how the package works out, that would be great if it works in R!
