_U_s_a_g_e:

     ## S3 method for class 'rpart':
     summary(object, cp=0, digits=getOption("digits"), file, ...)

_A_r_g_u_m_e_n_t_s:

  object: fitted model object of class 'rpart'.  This is assumed to be
          the result of some function that produces an object with the
          same named components as that returned by the 'rpart'
          function. 

  digits: Number of significant digits to be used in the result. 

      cp: trim nodes with a complexity of less than 'cp' from the
          listing. 

    file: write the output to a given file name. (Full listings of a
          tree are often quite long). 

     ...: arguments to be passed to or from other methods. 

_D_e_t_a_i_l_s:

     This function is a method for the generic function summary for
     class '"rpart"'.  It can be invoked by calling 'summary' for an
     object of the appropriate class, or directly by calling
     'summary.rpart' regardless of the class of the object.

_S_e_e _A_l_s_o:

     'summary', 'rpart.object', 'printcp'.

_E_x_a_m_p_l_e_s:

     z.auto <- rpart(Mileage ~ Weight, car.test.frame)
     summary(z.auto)
