prmatrix: Print Matrices, Old-style

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.

...

arguments for print methods.

Value

Invisibly returns its argument, x.

Details

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

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)
