As I recently tried several modeling techniques in R, I would like to share some of these, with a focus on linear regression.

Disclaimer: the code lines below work, but I would not suggest that they are the most efficient way to deal with this kind of data (as a matter of fact, all of them score slightly below 80% accuracy on the Kaggle datasets). Moreover, there are not always the most efficient way to implement a given model.

I see it as a way to quickly test several frameworks without going into details.

The column names used in the …

Let’s pretend you recently installed R (a software to do statistical computing), you have a text collection you would like to analyze or classify and some time to lose. Here are a few quick commands that could get you a little further. I also write this kind of cheat sheet in order to remember a set of useful tricks and packages I recently gathered and from which I thought they could help others too.

Letter frequencies

In this example I will use a series of characteristics (or features) extracted from a text collection, more precisely the frequency of each …
