rgcam is an R package provides functions for extracting data from GCAM output databases. The central concept in rgcam is the “project data file”, which contains an R-native representation of selected queries for one or more scenarios. The package provides functions to run the GCAM Model Interface to extract data and add the results to a new or existing project data file, as well as to manage previously created project data.
