Last fall I wrote a little script that might be useful for graduate students and faculty at my school: it checks to see whether a proposed faculty committee satisfies the university's requirements. You can read more about the project in this post. This script is now a usable web ...

what's vectorization?

In R, a "vector" refers to a one-dimensional array. A "vectorized" function f() takes a vector [x1, x2, ... , xn] as input and returns the vector [f(x1), f(x2), f(x3), ... , f(xn)]. If you'd like to read more about this, you should read Chapter 3 ...

A few weeks ago, I heard or read something like this: "if you look back at work you did a while ago and you think it was really awful, this is a good thing because it means you're improving."

I remember thinking this was a great attitude to have ...

Writing R packages is fun. Some people say you should start making your R code into a package as soon as you have two functions (just two!!). Making a package involves:

My sister is a senior undergraduate majoring in sociology. She just landed an awesome analyst job for next semester and was told she'll be using some R in the course of her work. She asked me to show her the ropes during winter vacation, and of course I said ...

"How long did that take to run?"

I think I've been asked that question approximately one bazillion times in the past few years. Unsurprising: I'm working in computational biology research. Whether we're developing our own methods or using our computing resources to analyze data for a collaborator ...

As I've spent more and more time writing code and analyzing data over the past few years, it's become increasingly obvious that developing a good, comfortable workflow is really important. Having a less-than-ideal step somewhere in your workflow is one of those situations where you don't even ...
