Linux editor for R+LaTeX, but not Emacs
Using Tinn-R (in windows) is possible to run latex and R from the same editor, which was great. Now, I am using Ubuntu-linux, which has been better than WinXP. Currently, I am using Emacs (and then install ESS) for running LaTeX and R from a same editor-program (like i was doing with Tinn-R in windows). Nevertheless, and even though i have been using Emacs for almost 2 years, it is not as

I am using R for Mac OS X GUI 1.35-dev Leopard build 32-bit. I have a network, g, of Chinese characters (each node is a Chinese character) and I can handle it and

R in Industry
The other day, CNN had a story on working at Google. Out of curiosity, I went to the Google employment web site (I'm not looking, but just curious).

When I started using Python, I noted they have a portion of the
