Data Mining of Google Analytics using R

Question

I am trying to use this code to access my Google Analytics API, but after running the code I get this error

Error in init_oauth2.0(self$endpoint, self$app, scope = self$params$scope. Unauthorized (HTTP 401). Failed to get an access token.

install.packages("RGoogleAnalytics")
install.packages("googleAuthR")
library(RGoogleAnalytics)
# Authorize the Google Analytics account

client.id <- "########################.com"
client.secret <- "#################_TknUI"
token<-Auth(client.id,client.secret)

Answer 1

This works for me:

library(RGoogleAnalytics)
oauth_token <- Auth(
  client.id = "XXXXXXXXXXXXXXXXXXX.apps.googleusercontent.com", 
  client.secret = "XXXXXXXXXXXXXXXXX"
)
oauth_token
# <Token>
#   <oauth_endpoint>
#   authorize: https://accounts.google.com/o/oauth2/auth
# access:    https://accounts.google.com/o/oauth2/token
# validate:  https://www.googleapis.com/oauth2/v1/tokeninfo
# revoke:    https://accounts.google.com/o/oauth2/revoke
# <oauth_app> google
# key:    XXXXXXXXXXXXXXXXXXXXXX.apps.googleusercontent.com
# secret: <hidden>
#   <credentials> access_token, expires_in, refresh_token, token_type

Maybe update your packages and/or the oauth endpoints?
