Or... if you really need to spend time in R, and shouldn't be wasting time with your favorite Web 2.0 watering holes, you can just update your tweets from R. I have done this from Excel but from R is just way much more cool. I might even tweet excellent tricks I learn in R at the times I learn them.

Problem is, this depends on Rcurl and Revolution R 64-bit doesn't provide it. And it's really hard to learn when new packages are added, because there's no easy way to diff the list of packages that exists now vs existed yesterday. And this is not the only package that is missing.

Thanks for the link back, Davo. I'm going to get your twitter handle tatooed to my ass in appreciation! So I've had some prompting to do a post on how to grab data online with RCurl and then parse it with R. Why don't you make my life easier and do a post on the topic and I'll just link to you... and drink beer. I'm lazy and you're good at this crap. If you don't know what data to use, you could start with ftp://ftp.cme.com/settle/. You know, if you don't have anything better to do.

BTW, your syntax is all pretty colors and stuff. Are you using a syntactic blog add in? Which one and how do you have it configured?

@j.d. long: I'll look out for a good example of online data processing. And for the pretty code, I just cut'n'paste from the REvolution R GUI on the Mac -- it has syntax highlighting.

I saw a demonstration of this a long time ago. I tried to do this using the code just now, but I get the following R error:

[1] "\n\n Basic authentication is not supported\n\n"
"application/xml" "utf-8"
Warning message:
In postForm(request, .opts = opts) : No inputs passed to form

Has something changed with Twitter such that this code needs to be amended?
