Hi, SPSSers

I was trying to create a custom node with Custom Dialog for R. I realize that the custom node I built cannot be added to the source palette. If I try, I get a error msg saying "Error saving dialog specification. You must have write permission to the deployment directory."

Is there any workaround on this? I want to add this node as a source.

Another problem is that I realized that whether it's the built-in three R nodes or a custom node, they all need to connect to a Modeler data source even if you don't use the data from the data source. In my custom node, I tried to cbind the new columns and records generated from my R code to modelerData after initializing modelerData <- {} but it didn't work. modelerData has to pre-exist and get passed down by previous nodes. Any workaround that?

Thanks!
