Defaults to 1. rdig: an optional integer value with the number of significant digits to be used in printing correlations. Defaults to 3. Level: an optional character string with a description of the grouping level associated with 'object' (generally corresponding to levels of grouping in a mixed-effects model). Defaults to NULL. resid: an optional logical value. If 'TRUE' an extra row with the '"residual"' standard deviation given in 'sigma' will be included in the output. Defaults to 'FALSE'. ...: optional arguments passed to 'print.default'; see the documentation on that method function. _A_u_t_h_o_r(_s): Jose Pinheiro Jose.Pinheiro@pharma.novartis.com and Douglas Bates bates@stat.wisc.edu _S_e_e _A_l_s_o: 'summary.pdMat','pdMat' _E_x_a_m_p_l_e_s: pd1 <- pdCompSymm(3 * diag(2) + 1, form = ~age + age^2, data = Orthodont) print(summary(pd1), sigma = 1.2, resid = TRUE)
