Some code to read in data from Google Analytics data. Some modifications include adding the SSL authentication code and modifying (in bold) the table.id parameter to choose correct website from a GA profile with many websites
The Google Analytics Package files can be downloaded from http://code.google.com/p/r-google-analytics/downloads/list
It provides access to Google Analytics data natively from the R Statistical Computing programming language. You can use this library to retrieve an R data.frame with Google Analytics data. Then perform advanced statistical analysis, like time series analysis and regressions.
Supported Features
- Access to v2 of the Google Analytics Data Export API Data Feed
- A QueryBuilder class to simplify creating API queries
- API response is converted directly into R as a data.frame
- Library returns the aggregates, and confidence intervals of the metrics, dynamically if they exist
- Auto-pagination to return more than 10,000 rows of information by combining multiple data requests. (Upper Limit 1M rows)
- Authorization through the ClientLogin routine
- Access to all the profiles ids for the authorized user
- Full documentation and unit tests
