...RODBC package within MS Access. I have been using from R but was just wondering if it could be used along with R(D)COM. Something like this: Dim dbs As DAO.Database Dim rst As DAO.Recordset Dim myApp As StatConnector Set myApp = New StatConnector myApp.GetErrorText myApp.Init "R" myApp.EvaluateNoReturn "library(RODBC)" myApp.EvaluateNoReturn "myDB <- odbcConnectAccess(CurrentDb)" 'query the database and save it as R object 'a' myApp.EvaluateNoReturn "a <- sqlQuery(CurrentDb, Paste(""select * From Sample""))" myApp.EvaluateNoRetur...

...(v1.2). I have written a custom function in R which returns a dataframe. I want to be able to retrieve the contents of the returned dataframe in my application. Here is a snippet of the code (line that throws exception). X has been correctly declared and init'ed earlier on in the code. x.EvaluateNoReturn("results_frame <- MyFunction()") I was intending to then invoke the GetSymbol method to retrieve the contents of results_frame into a local variable. I notice that this still dosen't work if I try to use the Evaluate method to directly assign the returned dataframe to my local...

Hi - I wrapped R.dll up using somebody code online (see below). I am comparing R on .NET IPC with R(D)COM. I got it all working. Except, I realize that in my client code of the IPC remoting, if I call 'plot' function in R via EvaluateNoReturn, I don't seem to see any results on the R plot window (although the window pops up). Is there anything to do with the code of R.dll wrapper below? I don't understand much of the code. But I have the feeling that graphic output was not specified to output correctly. Any help would be really...
