[R-pkg-devel] Help with making a package for Twitter Authentication

[Robert M. Flight]

Tushar,

I've created a Twitter App, and then saved the credentials for that app as
an object that is part of an R package, using the four pieces of *api key,
api secret, token key, token secret* that you get when you create a new
app. I've posted a tutorial here:
http://rmflight.github.io/posts/2014/06/r_job_notifications_twitter.html

The only thing I've found is that with new versions of some packages I may
have to regenerate the object and save it with the package.

Note that this method *should only be used with personal packages*, and the
credential object should never go into version control!

Alternatively, I think there may be a way to read in the four pieces from a
text file to generate the Oauth token object that can then be used for the
session. This might be a better method for a distributable package, and I'm
actually thinking of switching to this method myself, but have not tried it
yet.

I hope this helps.

-Robert
