So I need to get Traffic estimation for some keywords via Google Adwords. I see that Google has a traffic estimator service API: <https://developers.google.com/adwords/api/docs/guides/traffic-estimator-service> .

I'm using R, which has quite a comprehensive RAdwords package, <https://jburkhardt.github.io/RAdwords/faq/> , but one with which I failed miserably to find weather it provides access to this particular Adwords API service. 

So did anyone use R to get keyword data from Google adwords via Traffic estimator? Is it possible with the RAdwords packege or does it need to be done via classic scripting ? 

Thanks in advance.
