**Thinking inside the box**, and kindly contributed to R-bloggers)

I spent most of last week in Rennes, the capital of Brittany in France,

as it was time for

UseR! 2009,

the annual R conference. Francois Husson, Aline Legrand and others at the

Agrocampus Ouest had put together a really well-run conference, and it was a

pleasure to reconnect with so many people. It was also pretty nice to walk

around town and see bits and pieces of the

Tombees de la nuit festival

which happened at the same time.

As last year (and again at the BoC in December), I presented a three-hour

tutorial on high-performance computing with R. This covers profiling,

vectorisation, interfacing compiled code, debugging, parallel computing, as

well as scripting and automation. Slides, and a 2-up version, are now on my

presentations

page.

I also gave two regular conference presentations. The first was on my

Rcpp and

RInside packages

which facilitate interfacing R and C++. The second talk, based on joint work

with Charles Blundell, describes our cran2deb system for creating Debian

packages of essentially all CRAN

packages. I will try to follow up on this with another post. Slides from

these talks are also on my

presentations

page.
