Dear Thomas,
Thanks for the speedy reply, your help is much appreciated.
What I would like to do is to set up a mechanism for dynamically displaying graphs created using R, from data held in an Oracle database. I am using VB.NET to build the application.
So far, I have not made much progress, I have built a test application which attempts to use the R(D)Com Server to display a graph on a web page. I looked on the web for example code for the test, and came up with the following:
Dim xconnector As STATCONNECTORSRVLib.StatConnector
xconnector = New STATCONNECTORSRVLib.StatConnector
xconnector.Init("R")
Dim mygfx As New StatConnectorGraphicsDevice
this line should be the problem. You're creating a graphics device but
this device is never shown. Do not create mygfx using New but drop it on
a form. Or otherwise, add mygfx to some form (or whatever).
xconnector.AddGraphicsDevice("mygfx", mygfx.GetGFX())
xconnector.EvaluateNoReturn("plot(sin(1:100))")
xconnector.RemoveGraphicsDevice("mygfx")
xconnector.Close()
The rest of the code looks fine.
When I run the test, there are no errors reported but no graph displayed either.
Any ideas on where I am going wrong?
Hope this helps
Thomas
