(This post is the preliminary version of a book review by Alessandra Iacobucci, to appear in CHANCE. Enjoy !) As Rob J. Hyndman enthusiastically declares in his blog, “this is a gem of a book”. I would go even further and argue that The Art of R programming is...
I was a bit annoyed by the error when loading a dataset that contains multi-byte characters. R basically just chokes on them. I have not really understood the intricacies of this, but it was basically just an annoyance and since I did not really use these characters in the strings containing them, I just...
Sometimes it can be useful to list all the functions inside a package. This is done in the same way that you would list variables in your workspace. That is, using ls. The syntax is ls(pos = "package:packagename"), which is easy enough if you can remember it. Unfortunately, I never can, and have to...
As I was talking recently about reproducible research, I have to post this. A new paper by Eric Schulte, Dan Davison, Thomas Dye, Carsten Dominik. If you haven’t heard about them, you haven’t been on the org-mode mailing list. They could be called the main contributors to org-mode and the part of org-mode called...
My last post of substance was all about improving your performance using R to answer programming questions that might be asked during a job interview. So let's say you nailed the interview and got the job, but you desperately want to be fired for grand incompetence. Never fear, your pal at librestats once again...
My time as a grad student will soon draw to a close. With this comes the terrifying realisation that I'm going to start applying for jobs and, hopefully, interviewing soon, forever leaving my comfortable security blanket of academia. With that horrible thought in mind, I've been doing some poking around to see what various...
I came across a nice problem at project euler that gave me sense of satisfaction that was unusual, I think that because I don't usually get the solutions right the first time as I did in this case. Anyhow, I shall try and decode the R codes that I...
Mortgage rates are low, considering historical rates for the last 50 years. It may be timely to consider a mortgage refinance. The image above links to a simple tool for exploring mortgage refinance, built using rapache and the yet-to-be-archived yarr package for R. Hence, there are now two mortgage-related calculators on this site: MortCalc:...
I honestly have no book on R programming. In fact I have not a single book on programming at all (my coding proves that ;x). I am pretty sure that I am gonna order (just did!) that book. You can get a look of Matloff’s text here (= pdf for ya)
Couple of R programming (mainly infrastructure/workflow) related topics discussed at the Los Angeles R users group in a tutorial/demo-like form (targeted mainly to beginners) by Szilard Pafka and Jeroen Ooms: how easy it is to create a simple package for … Continue reading →
