[R] Extract table from a webpage

[Santosh Srinivas]

Dear R-group,

I've been able to use the XML package for getting relevant tables from
webpages for my analysis.
I'm stuck with this slightly more interactive problem involving clicking a
link

Fro this link .....

I want to get the data table into R. I was able to do it using XML .. but
now I want to get the whole list of 500 companies . for this . I need to
find a way to click on the "View All" link and then get the data into R
(hopefully).
Any suggestions how to go about it?

Thanks,
S
