Creating a Data.Frame using R.NET

Question

I'm using the R.NET project in C# to call R functions. Is there a way to create a DataFrame in C#? I see there is a DataFrame type here: https://rdotnet.codeplex.com/documentation

Currently I can create a data.frame in R by manipulating my data (integer values) into a series of strings and then using R.NET's evaluate command, but is there a way where I can push my data (integer values) to R without having to go through a string conversion process?

For example (and my ultimate question is), is there a way to create a DataFrame in C# using native integer values?

Thanks in advance.

Answer 1

The REngine object has a method CreateDataFrame, and this is the preferred way to create data frames.

You'll find example usage in the R.NET unit tests.

Another example can be found in an optimisation log extraction utility
