John Tukey’s preface to Exploratory Data Analysis begins with a useful rule, “It is important to understand what you can do before you learn to measure how well you seem to have done it.” When I decided I wanted to start a blog concentrating on statistics, R, and Emacs, I thought I had better learn 
I finally figured out how to use the R package "cachesweave". The trick is that the code chunks must follow some order, like the following:-----------------------------------------------------------=setCacheDir("testcache")@=library(Zelig)library(memis...
Development of the R package tikzDevice has been underway for about a month now. This package allows for the output of R graphics as TikZ commands. Charlie Sharpsteen and I have gotten it into an alpha stage. There is no real documentation but there is...
This tip may be useful in the situations when you need to set the number of digits to print for the different columns in a matrix/data.frame to be outputted as a LaTeX table. For example: #install.packages("xtable") #library(xtable) tmp <- m...
Most people using LaTex feel that creating tables is no fun. Some days ago I stumbled across a neat function written by Paul Johnson that produces LaTex code as well as LaTex code that can be used within Lyx. The output can be used for regression models and looks like output from the Stata outreg 
I got rubber to work with auctex and sweave (Rnw) files with the help of this. Basically, combined with my other stuff, I tweaked my .emacs file to look like: ;;following is AucTeX with Sweave -- works ;;http://andreas.kiermeier.googlepages.com/essmaterials (setq TeX-file-extensions '("Snw" "Rnw" "nw" "tex" "sty" "cls" "ltx" "texi" "texinfo")) (add-to-list 'auto-mode-alist '("\\.Rnw\\'" . Rnw-mode)) (add-to-list
After adding support for the cacheSweave package (see here) I have also added support for the weaver package to my Sweave.sh script. The experimental version is available here. After testing and feedback I will upload it to CRAN. One can use this new f...
There are now many places where one can find "my" Sweave.sh shell script for running Sweave and post processing with LaTeX directly from the command line. I published first version of Sweave.sh here (web page of the department). Later I moved my pages ...
When you write a large structured document using LaTeX, it is wise to use \input{} and/or \include{} commands (see here for a nice description). However, you can not "fully" use these two commands with Sweave documents. You can use them, but when you w...
I have added support for caching to Sweave.sh script as implemented in cacheSweave R package written by Roger D. Peng. Now, one can set caching on for chunks that are time consuming (data import, some calculations, ...) and the Sweaving process will r...
