I don't have R on the netbook I'm writing this from, but I *think* the
following will work:

Dear all,
I am aware of the URLdecode(..) function and was wondering if there
was something similar for HTML?
For example, I would like to convert strings like this:
> x <- "isn't"
into this:
> "isn't"
Many thanks for your time,

Dear all
Lets say I have a plain text file as follows:
> cat(c("[ID: 001 ] [Writer: Steven Moffat ] [Rating: 8.9 ] Doctor Who",
+ "[ID: 002 ] [Writer: Joss Whedon ] [Rating: 8.8 ] Buffy",
+ "[ID: 003 ] [Writer: J. Michael Straczynski ] [Rating: 7.4 ]
Babylon [5]"),
+ sep = "\n",
Thank you guys, both solutions work great! Seems I have two new
packages to investigate :)

I only really need the base packages, but otherwise I suppose the most
useful for me are:
(1) RCurl
(2) plyr
(3) XML

Background: During my uni days, I was taught to use MAPLE, MATLAB,
SPSS, SAS, C++ and Java. Then after uni, several years went by without
me ever using any of them again and was told to just use Excel. Then I
started my PhD and was told I should start using R instead (something

Dear all,

It's been a while since I've
done this, but if memory serves, the basic process was to download
xpdf and add it to the windows path, thus making it accessable from
within R. Two methods follow:
Method One (easiest) - using the awesome ?system command:

To be honest, I've never figured this out either. However, if you're
familiar with the gmail way of threading emails, just bookmark and use
google groups:

It's the easiest way I've personally found, and has a very intuitive
interface.

It's been a long time since i read the tutorials, but 'I think', the
reason you get those notifications is because the html code is
malformed, meaning that some of the opening tags '' don't have
corresponding end tags etc.
The XML package seems rather good at working with malformed code, and

Not sure if my code was attached in that last post:
library(RCurl)
library(XML)
html <- getURL("http://www.omegahat.org/RSXML/index.html";)
html.tree <- htmlTreeParse(html, useInternalNodes = TRUE, error =
function(...){})

Cls59 is correct that there is a lot of example code, just look in ?
htmlTreeParse and you'll get most of what you need i think.
here's some simplified code I use a lot of (XPath expressions are used
to parse the code):

# google url

Hi Philip,
If i understood correctly, you just wish to get the urls from a given
google search? I have some old code you could adapt which extracts the
main links from a google search. It makes use of XPath expressions
using the lovely XML and RCurl packages:
