melt_check {reshape2} | R Documentation |
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 discrete
variables are id variables and all other are measured.
