pprint: Pretty Printing

In ramify: Additional Matrix Functionality

Description

Prettier printing for matrices and data frames.

Usage

pprint(x, ...)

## S3 method for class 'matrix'
pprint(x, rowdots = NULL, coldots = NULL, digits = NULL,
  ...)

## S3 method for class 'data.frame'
pprint(x, rowdots = NULL, coldots = NULL,
  digits = NULL, ...)

Arguments

x	An object of class "matrix" or "data.frame".
...	Additional optional arguments. None are used at present.
rowdots	Integer specifying the row to replace with ... notation. Default is 4.
coldots	Integer specifying the column to replace with ... notation. Default is 4.
digits	The minimum number of significant digits to be printed in values.

Details

For object of class "matrix" or "data.frame" (which are coerced to a matrix via the data.matrix function), pprint will replace all the rows starting from rowdots up to and including the second-to-last row with a single row filled with ...s. The same is applied to the columns as well. Hence a large matrix (or data frame) will be printed in a much more compact form.

Examples

pprint(randn(100, 100))
pprint(resize(1:100, 10, 10))
