# Construct a small test data testdata <- data.frame(region = c("north", "south", "east", "south", "east"), index = c(1:5)) # Construct a changing rule: combining south and east Bmat <- matrix(c(1, 0, 0, 0, 1, 1), 3, 2) colnames(Bmat) <- c("north", "south and east") rownames(Bmat) <- c("north", "south", "east") print(Bmat) # New data after transformation test <- ChangeRegion(testdata, Bmat, "region") print(test)
