galeShapley.checkPreferences | R Documentation |
This function checks if a given preference ordering is complete. If needed, it transforms the indices from R indices (starting at 1) to C++ indices (starting at zero).
galeShapley.checkPreferences(pref)
pref |
is a matrix with ordinal preference orderings for one side of the
market. Suppose that |
a matrix with ordinal preference orderings with proper C++ indices or NULL if the preference order is not complete.
