HTMLStart R Documentation
Start / Stop the automatic redirection of output to HTML files
Description
Add the automatic redirection of output to an HTML file. The R session is modified in the following way: a new prompt is proposed (by default HTML>) and each parsed command is also evaluated using HTML generic method, so that the user benefits of both a normal and a HTML output. Please read carefully the details below.
Usage
HTMLStart(outdir = tempdir(), filename = "index", extension = "html",
echo = FALSE, autobrowse = FALSE, HTMLframe = TRUE, withprompt = "HTML> ",
CSSFile = "R2HTML.css", BackGroundColor = "FFFFFF", BackGroundImg = "",
Title = "R output")
HTMLStop()
Arguments
outdir
physical directory to store the output
filename
name of the target HTML main file
extension
extension of the target HTML file (htm, html,...)
echo
should the parsed commands be written in the output? [boolean]
autobrowse
should the browser be invoked each time a command is issued? [boolean]
HTMLframe
should the output have a HTML frame structure? [boolean]
withprompt
prompt to display while using HTMLStart/HTMLStop
CSSFile
path and name of a CSS file to use
BackGroundColor
option bgcolor for HTML tag <body>
BackGroundImg
option background for HTML tag <body>
Title
string to pass to HTML <title> tag
Details
The user may need to know the following points which describe how R2HTML does work:
- Each parsed command is evaluated and the returned value is passed to the generic function HTML. This evaluation is assured by addTaskCallback function, which is used to add a specific task each time R has to parse an expression.
- A new environment is built, where internal variables such as physical path are stored. This environment is not visible by the user. It is destroyed when calling HTMLStop.
Value
no useful output is returned.
Note
The argument echo is very usefull for teaching purposes.
