Yesterday, I was creating a knitr document based on a script, and was looking for a way to include content from an R help file. The script, which was a teaching document, had a help() command for when the author wanted to refer readers to R documentation. I wanted that text in my final document, though.

(This article was first published on R-statistics blog » RR-statistics blog, and kindly contributed to R-bloggers) What are the top 100 (most downloaded) R packages in 2013? Thanks to the recent release of RStudio of their “0-cloud” CRAN log files (but without including downloads from the primary CRAN mirror or any of the 88 other CRAN mirrors), we can now answer this question...
In case you missed them, here are some articles from May of particular interest to R users: Billions of geotagged Tweets create a beautiful map of the world when plotted with the ggmap package.

So I just got yet yet another comment saying "you have a typo in your documentation". While I do appreciate these kind reminders, I think it might be a good exercise for those who want to try GIT and Github pull requests, which make it possible for y...

Because D3 network graphs can be manipulated in the browser–i.e. nodes can be moved around and highlighted–they're really nice for data exploration. They're also really nice in HTML presentations.

Should you choose to use Jekyll as your blogging platform, you will find many resources out there describing the setup process. This post is not about getting set up using Jekyll or Jekyll Bootstrap. It’s about establishing a good workflow...
I just finished fixing (hopefully all) the problems in the knitr book returned from the copy editor. David Smith has kindly announced this book before I do. I do not have much to say about this book: almost everything in the book can be found in the on...
Today I learned about two forthcoming R books that I'm now looking forward to. The first is Applied Predictive Modeling by Max Kuhn and Kjell Johnson. Max Kuhn is the author of the caret package, an extremely useful and powerful R package for fitting and optimizing all kinds of predictive models in R. It's available now on Amazon Kindle...
