data <- inline.data.frame(c(
  "model;    scenario;   region;   variable;           unit;         period;   value",
  "REMIND;   Baseline;   USA;      GDP per Capita|MER; US$2005/yr;   2010;     40000",
  "REMIND;   Baseline;   USA;      Population;         million;      2010;     300",
  "REMIND;   Baseline;   CHN;      GDP per Capita|MER; US$2005/yr;   2010;     7000"))

reg_vec = c(USA = "United States")
var_vec = c("GDP per Capita|MER" = "gdp",
           Population = "pop")

revalue.levels(data,region = reg_vec)
revalue.levels_(data,list(region = reg_vec, variable = var_vec))
