prmatrix {base} | R Documentation

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

### Details

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

### Value

Invisibly returns its argument, `x`.

### Examples

    prmatrix(m6 <- diag(6), row = rep("",6), coll=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)
