Print Matrices, Old-style


An earlier method for printing matrices, provided for S compatibility.


prmatrix(x, rowlab =, collab =,
         quote = TRUE, right = FALSE, na.print = NULL, ...)


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 NAs are printed. If this is non-null, its value is used to represent NA.
... arguments for print methods.


prmatrix is an earlier form of print.matrix, and is very similar to the S function of the same name.


Invisibly returns its argument, x.
