prmatrix package:base R Documentation _P_r_i_n_t _M_a_t_r_i_c_e_s, _O_l_d-_s_t_y_l_e _D_e_s_c_r_i_p_t_i_o_n: An earlier method for printing matrices, provided for S compatibility. _U_s_a_g_e: prmatrix(x, rowlab =, collab =, quote = TRUE, right = FALSE, na.print = NULL, ...) _A_r_g_u_m_e_n_t_s: x: numeric or character matrix. rowlab,collab: (optional) character vectors giving row or column names respectively. By default, these are taken from 'dimnames(x)'. quote: logical; if 'TRUE' and 'x' is of mode '"character"', _quotes_ ('"') are used. right: if 'TRUE' and 'x' is of mode '"character"', the output columns are _right_-justified. na.print: how 'NA's are printed. If this is non-null, its value is used to represent 'NA'. ...: arguments for 'print' methods. _D_e_t_a_i_l_s: 'prmatrix' is an earlier form of 'print.matrix', and is very similar to the S function of the same name. _V_a_l_u_e: Invisibly returns its argument, 'x'. _R_e_f_e_r_e_n_c_e_s: Becker, R. A., Chambers, J. M. and Wilks, A. R. (1988) _The New S Language_. Wadsworth & Brooks/Cole. _S_e_e _A_l_s_o: 'print.default', and other 'print' methods. _E_x_a_m_p_l_e_s: prmatrix(m6 <- diag(6), rowlab = rep("",6), collab =rep("",6)) chm <- matrix(scan(system.file("help", "AnIndex", package = "splines"), what = ""), , 2, byrow = TRUE) chm # uses print.matrix() prmatrix(chm, collab = paste("Column",1:3), right=TRUE, quote=FALSE)
