June 8, 2011
By

Just got an email linking to Reproducible Research: A Range of Response, in the new journal Statistics, Politics, and Policy 2(1) by David Banks, who is also the journal's editor. Interestingly, the commentary doesn't mention the journal's policy (if one exists) on the reproducibility of research submitted there. Banks' writing is easy to read, though

May 25, 2011
By

bout half a year ago, I wrote a post on the configuration of (pgf)Sweave and LyX, which was intended to save us some efforts in going through all the details during the configuration.

A Makefile is a simple text file that controls compilation of a target file. The key benefit of using Makefile is that it uses file time stamps to determine if a particular action is needed. In this post we discuss how to use a simple Makefile that compiles a tex file that contains a number

WebSweave?

April 6, 2011
By

A recent R-help post asks for examples of Sweave use for web appliations. I think there is very little out there; maybe nothing. Below is a proof of concept for web-based Sweave-ing with rApache. But, it will soon be possible to do this with R's built-in web server. The idea was to treat an Sweave

Teach Yourself How to Create Functions in R

As you can tell from my previous posts, I am diving in head first into learning how to program (and simplify) my analytical life using R.  I have always learned by example and have never really prospered from the “learn from scratch” school of thought.  As I follow along with some other fellow R programmers,

A Special Graphics Device in R: the Null Device

December 22, 2010

We can query the default graphics device in options(): getOption('device') In a non-interactive session, the default device is pdf(). This is why Sweave has to create a file named Rplots.pdf no
