Details

If id.vars or measure.vars are missing, melt_check will do its best to impute them.If you only supply one of id.vars and measure.vars, melt will assume the remainder of the variables in the data set belong to the other. If you supply neither, melt will assume character and factor variables are id variables, and all other are measured.
