Thanks to all the suggestions and links.  I'll check these out and see what might work best.  I think I'd prefer converting the R code to a RESTful API, but that will depend on the user's cooperation.  Thanks again!  -Edie

Hi Edith,

I think that there are several ways in which you can accomplish this. You can either try to call it using a C# wrapper as Armeen mentioned or you can also do it through a RESTful Web API call using the PowerScript's RESTClient object. But of course, both solutions require some additional code on the C# or R side of things.

So you might want to check which of the two options is best for you. Following you may find info on how to consume your R library with C#: https://www.codeproject.com/Articles/25819/The-R-Statistical-Language-and-C-NET-Foundations and you may find how you can convert your R project into a RESTFul Web API using R Plumber here: https://www.r-bloggers.com/2020/01/how-to-create-rest-apis-with-r-plumber/

Hope this helps. But if you need more help on how to consume the C# dll or the RESTful Web API, please do let us know.

Regards,

Hi Chris,

Thanks for the link.  I think, however, I need to do the reverse of what is shown in the tutorial.  I need to use Powerscript to make calls to R libraries (not use R to make calls to Powerbuilder).  I don't believe that R has an API.  I think I can make calls to R using C# but I'm not very familiar (at all) with C#.  For example, from a Powerbuilder menu or button event I need to call some R routines.  Is it possible to use C# code in one of those events, intermingled somehow with Powerscript?  Sorry if this is a totally ignorant question.
