googleAuthR - Google API R Client

Overview

This library allows you to authenticate easily via local use in an OAuth2 flow; within a Shiny app; or via service accounts.

The main two functions are gar_auth() and gar_api_generator().

gar_auth

This takes care of getting the authentication token, storing it and refreshing. Use it before any call to a Google library.

gar_api_generator

This creates functions for you to use to interact with Google APIs. Use it within your own function definitions, to query the Google API you want.

Summary

Auto-build libraries for Google APIs with OAuth2 for both local and Shiny app use.

R Google API libraries using googleAuthR

Here is a list of available Google APIs to make with this library. The below libraries are all cross-compatible as they use googleAuthR for authentication backend e.g. can use just one OAuth2 login flow and can be used in multi-user Shiny apps.

• googleComputeEngineR - Google Compute Engine VMs API
• searchConsoleR - Search Console API
• bigQueryR - BigQuery API. Part of the cloudyr project.
• googleAnalyticsR - Google Analytics API
• googleTagManagerR - Google Tag Manager API by IronistM
• googleID - Simple user info from G+ API for Shiny app authentication flows.
• googleCloudStorageR - Google Cloud Storage API
• RoogleVision - R Package for Image Recogntion, Object Detection, and OCR using the Google's Cloud Vision API
• googleLanguageR - Access Speech to Text, Entity analysis and translation APIs from R

Feel free to add your own via email or a pull request if you have used googleAuthR to build something cool.

googleAuthR now has an R package generator which makes R package skeletons you can use to build your own Google API R package upon. Browse through the 154 options at this Github repository.

Example Shiny app

An example shiny app with Google authentication is deployed to shinyapps.io here. It uses the example app that is available in system.file("shiny", package="googleAuthR")
