html: Convert an S object to HTML

Description

html is a generic function, for which only two methods are currently implemented, html.latex and a rudimentary html.data.frame. The former uses the HeVeA LaTeX to HTML translator by Maranget to create an HTML file from a LaTeX file like the one produced by latex. The resulting HTML file may be displayed using a show or a print method. The browser specified in options(browser=) for R (help.browser for S-Plus) is launched to display the HTML file. html.default just runs html.data.frame.

Usage

html(object, ...)
## S3 method for class 'latex':
html(object, ...)
## S3 method for class 'data.frame':
html(object,
  file=paste(first.word(deparse(substitute(object))),'html',sep='.'),
     append=FALSE, link=NULL, linkCol=1, linkType=c('href','name'), ...)
## S3 method for class 'default':
html(object,
     file=paste(first.word(deparse(substitute(object))),'html',sep='.'),
     append=FALSE, link=NULL, linkCol=1, linkType=c('href','name'), ...)
## S3 method for class 'html':
print(x, ...)
## S3 method for class 'html':
show(object)

Arguments

object

a data frame or an object created by latex. For show is an object created by html. For the generic html is any object for which an html method exists.

file

Examples

Run this code

x <- matrix(1:6, nrow=2, dimnames=list(c('a','b'),c('c','d','e')))
w <- latex(x)
h <- html(w) # run HeVeA to convert .tex to .html
h <- html(x) # convert x directly to html
options(browser='konqueror')  # use help.browser for S-Plus
h            # launch html browser by running print.html
w <- html(x, link=c('','B'))   # hyperlink first row first col to B
