In yihui/rnotebook: An R Notebook Based on JSON, Markdown, and knitr

Description

Create a notebook file based on the metadata (e.g.,title and author, etc) and the content.

Usage

newnb(file = tempfile("rnotebook", ".", ".Rnb"), title = getOption("rnotebook.title", 
    "An R Notebook"), author = getOption("rnotebook.author"), date = Sys.Date(), 
    ..., body)

Arguments

file	the notebook filename
title	the title of the notebook
author	the author of the notebook
date	the date for the notebook
...	other metadata for the notebook
body	the body of the notebook; a default list of content is used if not provided, otherwise it should be a list of sub-lists, with each sub-list being a list of elements type (text or code), src (source), and out (output); for type = 'code', src is a list of two elements options (chunk options) and code (source code)

Value

The notebook filename (a temporary file by default, with the prefix rnotebook). The metadata and content are written to the file as a JSON string.

Examples

f = rnotebook::newnb()
rnotebook::refresh(f)  # compile the notebook
file.show(f)

f2 = rnotebook::newnb('foo-test.Rnb', author = 'R. A. Fisher', body = list(
  list(type = 'text', src = 'Hello **world**.', out = NULL),
  list(type = 'code', src = list(
    options = '', code = 'fisher.test(matrix(c(3, 1, 1, 3), 2))'
  ), out = '')
))
file.show(f2)
rnotebook::refresh(f2)
