New Post: Creating DataFrame In Memory
Hi J-M, I got an error when creating DataFrame in memory: e.SetSymbol("dData", e.CreateNumericVector(dftData)); e.Evaluate("print(dData)"); var df = e.Evaluate("data.frame(X=dData").AsDataFrame();...

Not sure this is it, but you are missing a closing bracket in the string.var df = e.Evaluate("data.frame(X=dData").AsDataFrame()should bevar df = e.Evaluate("data.frame(X=dData)").AsDataFrame()

Yes, it is the one causes the null problem :D But next line:var df = e.Evaluate("data.frame(X=dData)").AsDataFrame(); e.Evaluate("print(X)"); generates:Error in print(X) : object 'X' not found

Hi, Please describe your problem in a reproducible manner.

Shifting the discussion back to nullable boolean arrays. I think it should be easy enough to create my own class inheriting from Vector<bool?>. The only problem is that the ProtectedPointer class...

Hi, I'm getting EntryPointNotFoundException for the function R_ReleaseObject. I'm using R version 2.15.3 and probably this method is not implemented there. Is it possible to configure R.Net to be aware...

Noted; I'll look at it in the coming days if I can (got to deal with pressing deadlines). If you are on Windows, I'd recommend you have a look at CFF Explorer suite to see what functions R.dll exports.

Yes I think I see what you mean. If you feel up for it (there is no harm trying), you can create a fork of the repository for your own needs, with the possibility to submit a pull request. I am not...

The function is exposed from R.dll and I actually see it being resolved successfully multiple times. I think it might be a race condition, where the handle is being closed before all objects are being...

I think I found the issue. I'm setting attributes on some vectors. To do that I create a character vector to hold the attribute value. This vector is never disposed, so at the final GC, its finalizer...

Hi, I have a list, which has Date and Utilization value. In R.net dll, there is not option to handle list directly. Either i need to convert to 2D array or matrix or create 2 Vector. After taking the...

I have no idea what a utilization value is but it sounds like you have two data types. I would load each in to R and then evaluate a cbind command in the engine.

yes, its 2 different datatypes in a list.

Found more info on this issue. There are a lot of places in the code where a safe handle object is created and not disposed. All the calls to GetPredefinedSymbol leave a safe handle object...

This sounds like issues that have been dealt with on the development branch 'jperraud'; certainly the leakages with character vectors. You may want to work from that branch; it looks like you have no...

Hi, I have not checked the default branch, but you probably bumped in an issue. I know I repeat myself from other posts, but for the sake of future readers, can you use the branch 'jperraud'? data...
