Hi Ron,
It looks like the data you want is generated by javascript; if so
Rcurl will not be able to retrieve it for you. See
http://stackoverflow.com/questions/14491598/how-do-i-download-the-source-code-for-a-webpage
and
http://stackoverflow.com/questions/9778076/how-to-view-webpage-source-code-using-r?rq=1
for some ideas to get you started.
Best,
Ista
