gslider-gwidgets
Hello R lovers,
For my GUI, I am using gslider of Gwidgets. I need to add the "to=" value
dynamically ie., maximum value from a data frame column(something like
to=max(df[,3])). But I am getting error message like
Error in checkPtrType(object, "GtkWidget") :
object of class NULL isn't a GtkWidget
Not sure what I am missing here!!!
Regards,
karthick
