Off-topic -- an eye on a stats presentation for clinicians?
I've got a 20 slide Powerpoint set up against the expected day someone says "Mitch, could you talk for a short while to the residents on how to use statistics?" It looks good at this end, but I'd love to get at least one more pair of eyes on it.

finding yap.exe with Sweave
Dear all: Just to make sure I am on the same page as everyone else. I just got a new computer and had to reinstall MikTex and of course R and Tinn-R. In order to be able to generate PDF's with Sweave I had to install notepad++ to tell Sweave where Latex.exe and yap.exe where located under MikTex path. So,I have two questions: 1- Do I need to have a Miktex editor in order to use Sweave? I am

how to use \Sexpr{} with sweave
I'm trying to learn Sweave. So far things are going well with the chunks of code identified by << >>= But I'm having trouble with the in-line text use of \Sexpr. Here is a short example .Rnw file: \documentclass[12pt]{article} \usepackage[margin=1.25in]{geometry} \usepackage{graphicx} \usepackage{Sweave} \begin{document} <<test>>= pnorm(1) @ \Sexpr{2+6}

cronbachs alpha - score.items(psych) vs reliability(Rcmdr)
Dear all, I like the way the Rcmdr package computes reliability. E.g reliability(cov(d[,c("q1", "q2", "q3", "q4", "q5", "q6")], use="complete.obs")) will not only give me the alpha score, but also for each variable, alpha.score if deleted. However - when writing scripts it's very tiresome to load the whole Rcmdr GUI just

Staging area for data before read into R

Stat textbook recommendations?
Hello, I'm looking for a textbook that can explain some of the math behind the intro-to-intermediate stuff like ANOVA, multiple regression, non- parametric tests, etc. A little background: I took an intro stats course last year and would like to further my education. Being as that was the highest (and only) stats class the local community college offers, it looks like I'm on
