+## If the first argument is a vector and the second is a matrix, the

+## If both arguments are vectors, the elements of y are plotted versus

+##
+## If both arguments are matrices, the columns of y are plotted versus

+## number of rows and columns and no attempt is made to transpose the
+## arguments to make the number of rows match.
+##
+## If both arguments are scalars, a single point is plotted.
