I’ve had enough of copy and pasting output from my R session into my email editor, blog, etc. I need something like Sweave for plain text files. In particular, I want the result of parsing <<echo=TRUE>>= f <- function(x) { x + 1 } f(1) @ with Sweave, but without the latex markup. For example,

Asher’s enigma
On his Probability and statistics blog, Matt Asher put a funny question (with my rephrasing): Take a unit square. Now pick two spots at random along the perimeter, uniformly. For each of these two locations, pick another random point from one of the three other sides of the square and draw the segment. What is 
Building an R package (under Windows) without C, C++ or FORTRAN code
Why build and R package? It basically boils down to be able to brag at your local pub that a new version of YOUR package is on CRAN as of 7 p.m. CET. But seriously, if you’ve produced some function that other people might benefit (or have ordered them) from using them, like your boss, 
Creating a Presentation with LaTeX Beamer – Equations and tikz
Many presentations created using LaTeX beamer included mathematical equations and these can be easily included in a presentation and in this post we will consider using the tikz package to add various interesting elements to equations, such as lines between text on a slide and part of an equation. Fast Tube by Casper The examples on this
Creating a Presentation with LaTeX Beamer – Boxes
We can add coloured boxes with text or mathematics into a LaTeX beamer presentation which is particularly useful if we have definitions, theorem or computer code to highlight this information that may not be so accessible within a paragraph of text. Fast Tube by Casper The easiest way to create a box is to use the various
Cherry Picking to Generalize ~ retrospective meta-power analysis using Cohen’s f^2 of NASA temp + visualization
Previously, I plotted a grid of NASA GISS global temps in ggplot2 to show general trends by the brute force method. Here, I will again use the brute force method to do a simple power analysis on a portion of the data (data here). The general aim is to figure out what the minimum sample

The StackExchange site on Statistical Analysis is about to go into private beta testing. This is your last chance to commit if you want to be part of the private beta testing. Don’t worry if you miss out — it will only be a week before it is then open to the public. There is
Creating a Presentation with LaTeX Beamer – Tables
Tables of information can be included in a LaTeX beamer presentation in the same way that they would be incorporated into any other LaTeX document. The tabular environment is used and, if necessary, the tables could be numbered but this probably doesn’t make as much sense as labelling and numbering tables within an article or
Multidimension bridge sampling (CoRe in CiRM [5])

Since Bayes factor approximation is one of my areas of interest, I was intrigued by Xiao-Li Meng’s comments during my poster in Benidorm that I was using the “wrong” bridge sampling estimator when trying to bridge two models of different dimensions, based on the completion (for and missing from the first model) When revising the

Still drudging along preparing the new edition of Bayesian Core. I am almost done with the normal chapter, where I also changed the Monte Carlo section to include specific tools (bridge) for evidence/Bayes factor approximation. Jean-Michel has now moved to the new hierarchical model chapter and analysed longitudinal datasets that will constitute the core of
