In my previous post I wrote about how to identify and visualize package dependencies.  Within hours, Duncan Murdoch (member of R-core) identified some discrepancies between my list of dependencies and the visualisation.  Since then, I fixed the dispecrancies. In this blog post I attempt to clarify the issues involved in listing package dependencies.

As global warming causes sea levels to rise, the risk of flooding for coastal settlements also rises over time. A recent analysis by Reuters find that incidents of coastal flooding along the Eastern seaboard of the United States have surged in recent years as the sea level steadily rises.


Pearl Jam has been featuring in my playlist recently, which reminded me of this old Misheard Lyrics video for Yellow Ledbetter:


The funny think is, I don't think Yellow Ledbetter has official lyrics, so these might be as good as any. I've seen it performed a few times on stage, and each time the lyrics are different. Not as wildly divergent as these, but still: variations each time. (If anyone does know what the actual lyrics are, please point me to the source!)

That's all for this week. See you Monday!

I was honoured to be invited earlier this month to the Directions of Statistical Computing meeting in Brixen, Italy. DSC is one of two meetings run by the R Project and unlike the useR! conference, DSC is a much smaller and intimate meeting (DSC 2014 had about 30 participants).

R is a functional language, which means that your code often contains a lot of ( parentheses ). And complex code often means nesting those parentheses together, which make code hard to read and understand. But there's a very handy R package — magrittr, by Stefan Milton Bache — which lets you transform nested function calls into a simple pipeline of operations that's easier to write and understand.

Statistics has many canonical data sets. For classification statistics, we have the Fisher's iris data. For Big Data statistics, the canonical data set used in many examples is the Airlines data.

This blog has its fair share of typos and homophones, I know. There's always room for more proofreading. (And don't get me started on the inconsistent use of "favorite" and "favourite" — my spelling locus is drifting somewhere in the mid-Pacific these days.) But I am a bit of a grammar nerd, so I appreciate Weird Al Yankovic's attempt to get the social media set to use words proper-like (and also get off my lawn!).
