My EIAdata R package is now available on CRAN. This means you can install the package with a simple,
install.packages("EIAdata") from within R.
A development version of the package is available on GitHub. This package gives you programmatic access, from within R, to over a million energy related time series available through the Energy Information Administration's API.
The report is here.
I just put my functions to interact with the EIA's API into a R package which I've called 'EIAdata'. The package is available here: EIAdata_0.1.tar.gz. Once downloaded, you can install it with
R CMD INSTALL EIAdata_0.1.tar.gz while in the same directory.
The package contains the functions
getEIA which will get data categories/series IDs, and the time series data for a given series ID, respectively.
I posted a new working paper HERE. It is a short letters type paper---so it is a quick read. In the paper we show four standard portfolio performance measures (Sharpe Ratio, Jensen's alpha, Information Ratio, and Treynor Ratio) all rank portfolios consistently (all measures have a preference for portfolios with a greater number of stocks). The implication is, it doesn't matter which portfolio measure you use, each will afford a very similar ranking for a given set of portfolios.

You can watch the World Cup live (or should I say 'en vivo') at Univision here: http://deportesenvivo.univision.com/. Of course, the play by play is in Spanish. If you want to English play by play, a Bloomberg article has a work around.
I just listen to the Spanish announcers -- if you know a bit of Spanish you can generally get the idea of what they are saying. And anyway, they are much more fun to listen to when a goal is scored.
A little while ago, my Debian sid system stopped mounting CDs. Shortly thereafter it stopped mounting USB devices also. After searching around a bit I found a solution here (the problem was with Consolekit): https://lists.debian.org/debian-user/2011/10/msg01252.html
The solution is to create a file
etc/polkit-1/localauthority/50-local.d/consolekit.pkla with the contents:
Identity=unix-user:your username here
of course replacing your username here. Also create
/etc/polkit-1/localauthority/50-local.d/udisks.pkla with the contents:
Hope this helps if you run into the same issue.
