	_A_r_g_u_m_e_n_t_s:
	
	      object : an object containing the results returned by
	               a model fitting function (e.g. lm or glm).
	
	         ... : additional objects of the same type.
	
	_V_a_l_u_e:
	
	     This (generic) function returns an object of class
	     anova.  These objects represent analysis-of-variance
	     and analysis-of-deviance tables.  When given a single
	     argument it produces a table which tests whether the
	     model terms are significant.
	
	     When given a sequence of objects, anova tests the
	     models against one another in the order specified.
	
	     The print method for anova objects prints tables in a
	     ``pretty'' form.
	
	_S_e_e _A_l_s_o:
	
	     coefficients, effects, fitted.values, residuals, sum-
