[R] COM objects with early bindings in R

[Pfaff, Bernhard Dr.]

Dear list member,

I am using the packages RDCOMClient and SWinTypeLibs and try to import a COM
object (created in Delphi) in R that is of type 'early binding' instead of
late 'late binding'. Is there a possibility to do this in R?

Currently, the following returns an error message:

l1 = LoadTypeLib("c:\\Programme\\INVESCO\\QaCalendar\\Calendar.dll")
print(getTypeLibTypes(l1))
      IQaCalPeriodicInit            QaCalPeriodic            IQaSeriesInit 
              "dispatch"                "coclass"               "dispatch" 
                QaSeries                _QaSerLib                 QaSerLib 
               "coclass"               "dispatch"                "coclass" 
      IQaCalSporadicInit            QaCalSporadic           _QaCalendarLib 
              "dispatch"                "coclass"               "dispatch" 
           QaCalendarLib QaCalendarIntersectRules          QaDistanceRules 
               "coclass"                   "enum"                   "enum" 
createCOMSClass(l1[["QaSerLib"]], "test")
Error in generateOperators(libEntry, className) : 
	invalid subscript type  

Any help, pointers or a working example is much appreciated.

Best Regards,
Bernhard
