     ## S3 method for class 'princomp':
     summary(object, loadings = FALSE, cutoff = 0.1, ...)

     ## S3 method for class 'summary.princomp':
     print(x, digits = 3, loadings = x$print.loadings,
           cutoff = x$cutoff, ...)

_A_r_g_u_m_e_n_t_s:

  object: an object of class '"princomp"', as from 'princomp()'.

loadings: logical. Should loadings be included?

  cutoff: numeric. Loadings below this cutoff in absolute value are
          shown as blank in the output.

       x: an object of class "summary.princomp".

  digits: the number of significant digits to be used in listing
          loadings.

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

     'princomp'

_E_x_a_m_p_l_e_s:

     data(USArrests)
     summary(pc.cr <- princomp(USArrests, cor=TRUE))
     print(summary(princomp(USArrests, cor=TRUE),
                   loadings = TRUE, cutoff = 0.2), digits = 2)
