similar to: RODBC and RDCOM

I am using RDCOM as a data-transfer between R and C#.net. I got a question on datasets with missing data. For instance, if list = c(1,2,3,NA,5), in R, typeof(list) is integer but, in C#, I did not see a suitable data type for (1,2,3,NA,5). Of course, one can use is.na to transfer (1,2,3,NA,5) into string[] in C#. So, how to handle NA in this case? Please help. Thank, -james

Dear All, I am using excel.link package to open and modify Excel files. When I manually open Excel, all my add-ins are loaded without a problem. But when I open Excel using excel.link package, like: xls<-xl.get.excel() xl.workbook.open("MyFile.xlsx") some Excel add-ins are (installed but) not loaded. Since the problem is related to local add-ins at my side, I cannot reproduce the

Hello I am using Duncan Lang's RDCOM Client package (available on omegahat.org) under R 1.7.0 and Windows XP Pro. Is this the right forum for questions about this package? In case it is, here is my question: Instances of COM objects do not seem to terminate as expected, but leave residual processes running. For example, if I try the simple example: E <-

Dear list members, When I modify the MFC sample (using the statconnector graphics device) to show a lattice graph in the Active X control (actually the wireframe from http://addictedtor.free.fr/graphiques/graphcode.php?graph=40 ) the program runs without generating any errors, but the data-driven part of the plot does not display. The bounding box is displayed, but not the axes or data within

Full_Name: Edward J.

Hi. My VB program run a R - script located in the server with R DCOM server. The R - script is designed to send a query to DB through ODBC.

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.

Is there anything to do with the code of R.dll wrapper

Hi, I'm trying to combine a VBA macro and a R package. I've installed the R-(D)COM and the R-excel interface by Neuwirth. They seem to work both.
