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

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). In perusing their job posts for statisticians, preference is given to those who use R and python. Other languages, S-Plus and something called SAS were listed as lower priorities. When I started using Python, I noted they have a portion of the

From S-Plus to R
Dear Isabelle, for most of my work I have switched from S-Plus to R, because it is easier to make scripts with due to the better documentation and some other more reasonable implementations. And there was also a cost issue with the S-Plus Server, which is not for free at all. In R I use the its package for time series, which is quite sufficient for my needs. The only problem I encountered was

ext3 Patch doesn't work with 2.4.13
Hi, I just wanted to compile my kernel 2.4.13 with the ext3-2.4.13-pre6 patch, but it doesn't work. It seems, that the patching failes by replacing some things in a textfile. Does anyone of you know, if there is a upcoming solution for this? Kind regards Jan Albrecht -- Jan Albrecht Phone: +49-5241-80-88404 System Consultant UNIX/NT Fax:

R-beta: wish: hist() returning breaks and counts
Hi, would it be possible to change the hist() function in future R Versions to accept a "plot=F" parameter (like hist() in S it should return a list with "breaks" and "counts" in this case). This change should be very simple. Albrecht ------------------------------------------------------------------------------- Albrecht Gebhardt email :
