# R code
# Based on https://stackoverflow.com/a/23810363/633251
# This is called "Web Application Flow"
# see https://developer.github.com/apps/building-oauth-apps/authorizing-oauth-apps/#web-application-flow
# Follow the instructions there to set up a token.  Never share your key or secret.

library("httr")
myapp <- oauth_app("FOSS", key = "pqr", secret = "xyz")
github_token <- oauth2.0_token(oauth_endpoints("github"), myapp)

# In the R console you will have the option to save an authorization file
# or do a one time authorization.  Then a web page will open with a message
# and you can close it after reading the message.
# The object github_token is now in your workspace can can be called when
# accessing the Github API
