The Financial Times publishes Excel files on their website: http://www.ft.com/cms/s/0/988051be-fdee-11e3-bd0e-00144feab7de.html#axzz3MBmtHOiy.
I don't know anything about R, except that it can load files and then you can look at them. How does one open a file that's on the internet and not on my local hard disk so that I can load them directly into R without downloading them?
The exact file I want is the FT Global 500: http://im.ft-static.com/content/images/7097ad1a-fded-11e3-bd0e-00144feab7de.xls
