Abstract:
|
There many tasks that we perform time and time again when performing a data analysis, particularly during the early data cleaning and exploration phases. Identifying and explicitly describing these tasks makes data manipulation faster and easier because you don't need to think so much---you can just use a standard tool from your mental toolbox. In this roundtable, I'd like to talk about one pattern that I've identified, split-apply-combine, and discuss with you what other patterns might be. My work in this area has focused on R, but I think the topic is general enough that it shouldn't matter what software you use.
