coef.opm returns the best parameters found by each method that
returned such parameters. The returned coefficients are in the form of a
matrix with the rows named by the relevant methods and the columns named
according to parameter names provided by the user in the vector of starting
values, or else by "p1", "p2", ..., if names are not provided.
