# Recode a GADS
pisa2 <- recodeGADS(pisa, varName = "schtype",
                        oldValues = 3, newValues = 9)
pisa2 <- recodeGADS(pisa2, varName = "language",
                        oldValues = 1, newValues = 15)

# Compare
compareGADS(pisa, pisa2,
            varNames = c("ganztag", "schtype", "language"), output = "list")
compareGADS(pisa, pisa2,
            varNames = c("ganztag", "schtype", "language"), output = "data.frame")
compareGADS(pisa, pisa2,
             varNames = c("ganztag", "schtype", "language"), output = "aggregated")
