See [this discussion](https://rdotnet.codeplex.com/discussions/539844).Started a unit test; now that function calls with dotted pairlists works, calling the data frame function is much easier. Feature...

Thank you for your reply. Is there a way to handle missing values? For example, if my column is int?[], how can I create an integer vector to represent this? Thanks, Yoav. Looking forward for v1.6!

Ok, I think I figured it out. For integers I need to pass in Int32.MinValue and for doubles I need to pass in double.NaN.

Does R.NET support "Skew Normal Distribution" such as snorm or others similar functions?

It depends what you mean, really; could you be more precise. Do you have a short R code illustrating what you would do in R? If you can express something in our R statements, you probably can craft an...

What I need is to create a skewed normal distribution curve that fits a histogram in C# and .NET. In searching the library, I found one in R - the "sn" library. e.g. data(mydata, package="sn")...

Using some sample code from the package, the following works: private static void ReproDiscussion540017(REngine e) { e.Evaluate("library(sn)"); e.Evaluate("data(wines, package='sn')"); e.Evaluate("X...

Hi again. It seems like there is a problem with logical arrays with missing values. Doing this: e.Evaluate("a <- c(0,1,NA,1)").AsLogical(); will result with "false, true, true, true". And I can't...

Your code works! Now I learned how to link the library and call functions in R. I also learned how to pass the results back to .NET. To make this works in my .NET application, I need to pass the data...

This is not supported via nullable booleans; however you can do the following to identify NAsvar boolVals = e.Evaluate("a <- c(0,1,NA,1)").AsLogical().ToArray(); var missingValuesAt =...

Is there a plan on changing it in the future and support nullable bool arrays (both as inputs and as outputs)? Shouldn't this be relatively simple, as booleans are represented as integers in R and the...

Quick question about nullable boolean arrays. Is it possible to use integer vectors instead of logical vectors when passing in (and out) nullable boolean arrays to R using R.Net? From the R...
