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 
Here you can find a very interesting post depicting the R strengths in 'real-time statistics'. I'd like to use the occasion to thank David Smith for hosting the best, imho, blog on R! Follow Him on Twitter: @revodavid .

Just recently, I was contacted by a researcher who wanted to use influence.ME to obtain model estimates from which iteratively some data was deleted. In his case, observations were nested within an area, but there were very unequal numbers of ...
Hierarchical clustering is a technique for grouping samples/data points into categories and subcategories based on a similarity measure. Being the powerful statistical package it is, R has several routines for doing hierarchical clustering. The basic command for doing HC is hclust(d, method = "complete", members=NULL) Nearly all clustering approaches use a concept of distance. Data points
