Read GCAM Data

For a full list of available params for this function please see colors, maps and params. metis.readGCAM will return a list containing:

• data: a dataframe with the original data
• dataAggParam: a dataframe with the data aggregated to the parameter
• dataAggClass1: a dataframe with the data aggregated to class 1
• dataAggclass2: a dataframe with the data aggregated to class 2
• scenarios: A list of the scenarios
• queries: A list of the queries used to extract the data

library(metis)


dataGCAM <- metis.readgcam (
       #gcamdatabase = “Path_to_GCAMdatabase”,
       dataProjFile = metis::exampleGCAMproj)

df <- dataGCAM$data; df
dfParam <- dataGCAM$dataAggParam; dfParam
dfClass1 <- dataGCAM$dataAggClass1; dfClass1
dfClass2 <- dataGCAM$dataAggClass1; dfClass2
