@robertzk was this intended ?

Now passing api_token parameter to hipchat() function does not do anything since hipchat_send takes by default api_token = hipchat_api_token()

So using hipchat(api_token = 'my_own_token') under the hood is actually hipchat(api_token = hipchat_api_token())

And this means you will no longer have to follow the instruction from README.md

You will need to have a HIPCHAT_API_TOKEN in your environment variables, or set a options(hipchat.api_token = 'your_api_token') in your ~/.Rprofile.
