Hello..!!!
  I got a problem while built R program with tcltk. I try to list the name of all data frame in my memory by "tklistbox". when we choose the name of data frame, then i capture the name, and catch the data frame by    

  tclObj(dat)<-as.data.frame(get(x,envir=.GlobalEnvir))   tclvalue(dat)    

  where x is the name of the data frame.The error is "Cannot handle object of mode "list"". Note, that i have assign variable "dat" by "dat<-tclVar()". so that it can be accesed by another function in my program. I have tried things like this, and it can work well. But why this time cannot work well?    

  Please tell me what happen and how to fix it.    

  Thank You
