I am trying to use the forecast.holtwinters function and when I try to run it:
dftimeseriesforecast <- forecast.HoltWinters(data, h=65)
I get this error:
Error: could not find function "forecast.HoltWinters"
I have also tried this:
dftimeseriesforecast= forecast::forecast.HoltWinters(data, h=65)
But I get this error message:
Error: 'forecast.HoltWinters' is not an exported object from 'namespace:forecast'
I look at this list of functions in the forecast package using this code:
ls("package:forecast")
and this returns:

Does anyone know what is going on? I've used this before and had no problems. I'm using forecast version 8.1.
