printr

Build Status

This is a companion package to knitr. Its main purpose is to extend the S3 generic function knit_print() in knitr, which is the default value of the chunk option render, as explained in the vignette knit_print.html.

It has not been released to CRAN yet, and you can install the development version from my personal repo for now:

install.packages(
  'printr',
  type = 'source',
  repos = c('https://xran.yihui.name', 'https://cran.rstudio.com')
)

To enable the printing methods defined in this package, just library(printr) in a code chunk (in the beginning) of your knitr document. Then some objects will be printed differently with what you would have seen in a normal R console. For example:

For more information, please check out the package vignette:

vignette('printr', package = 'printr')

You are welcome to contribute more S3 methods to this package, and you may want to read the existing methods in this package before you get started. In most cases, I guess you will end up rendering either plain text (see knit_print.packageInfo for example) or tables (see knit_print.matrix) in the output.
