I am not sure how i feel about sequence analysis companies marketing to clients the fact their infrastructure is based "in the cloud". Would a surgeon brag about renting an operating room?

PhillyR meeting tomorrow night:
Investigating 100 years of dialect history.
For 40 years, researchers at the University of Pennsylvania's Linguistics Lab have been interviewing every day Philadelphians. Recently, we have been engaged in a project to take this catalogue of interviews, which mostly exists on reel-to-reel magnetic tape,and apply modern technological advancements in audio processing to generate a large and rich data set of dialect information. We have used R at many stages of the process from the acoustic analysis (using the python package rpy2), to the data refinement and manipulation, to data visualization, to statistical analysis of the results. I'll discuss the role R played, and show you some examples of language change in motion.

Headline: Decade-old Sweave limitation removed in 5 minutes.
+Yihui Xie is doing some great things with knitr.

The inability to hide chunks dynamically was always a big annoyance with Sweave, especially with figures. Yes, there were LaTeX hacks, and other weavers, but knitr offers a real solution using traditional syntax. All it took was me asking for it.

Below is a toy example, but you can see the possibilities in terms of developing truly dynamic reproducible reports:



\documentclass{article}
\begin{document}

<<setup,echo=FALSE>>=
dothis<-c(FALSE,TRUE,TRUE)
showthis<-c(FALSE,FALSE,TRUE)
@

<<dontdothis,echo=showthis[1],eval=dothis[1]>>=
print("I am not even doing this!")
@

<<dothis,echo=showthis[2],eval=dothis[2]>>=
print("I am doing this!")
@

<<showandtell,echo=showthis[3],eval=dothis[3]>>=
print("I am doing this and showing you how!")
@
\end{document}

This seems like something that would sound logical to venture capitalists but not to actual core facility managers. I would like to hear what other think.

at first I was all like "this was a stupid question" but then i was all like "this is just my kind of question"

another reaction to my "Big-Ass Servers™ and the myths of clusters in bioinformatics" post - so many hits on that post and only a fraction were from people looking for big asses.
