Description

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

Usage

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

Arguments

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.

Details

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