Hi everybody,

I'm using NetBeans and RCaller to build a little GUI in Java. Within the code I'm reading .fcs files using read.FCS from the flowCore package. When I add the code to the R console everything works fine. If I run the code in Netbeans the following error occurs: 
Error: Error in isVersioned(object) : 
Error: error in evaluating the argument 'object' 
Error: for function 'isVersioned': error in `[<-`(`*tmp*`, names(versions), value = list()) : 
Error: could not find function "loadMethod"
Error:Calls: as ... asMethod -> new -> initialize -> initialize -> .local -> [<-
Error:Calls: read.FCS ... validObject -> anyStrings -> validityMethod -> isVersioned
Error: Execution stopped

I set:

I would be very thankful for any help.
