I am doing some predictions using R.NET - making data frames, running linear regression and then using predict method to obtain predictions. Everything run ok, until suddenly, I received (and received from then on):
```
RDotNet.EvaluationException: Unable to retrieve an R error message. Evaluating 'geterrmessage()' fails. The R engine is not in a working state.
```
What causes this, or how can I fix this - should I reinitialize the engine?
Thanks
Comments: What version of RDotNet are you using? Do you have your code available? Can you boil it down to a test case? You can't currently reinitalize the R engine as it is a bunch of unmananged C dll's that are loaded into the managed process space. I'm working on a solution to host the engine out of process, but it is very much in development.
