Profiling and Optimizing,In this last chapter, we will briefly consider what to do when you find that your code is running too slow and, in particular, how to figure out why it is running too slow.

We return to it later, when we have a little more experience using R. The good news is, though, that to use R for data analysis, we rarely need to do much programmin

N. J. Strausfeld,J. A. Campos-Ortegaking prediction models. Sometimes, we are just trying to find out what structure is actually in the data we analyze. There can be several reasons for this. Sometimes, unknown structures can tell us more about the data. Sometimes, we want to explicitly avoid unknown structures (if we have datasets th

Molecular Computing by Signaling Pathways, book. In the first chapter, you took a tutorial introduction to R programming, but we left out a lot of details. This chapter will cover many of those details, while the next two chapters will cover more advanced aspects of R programming: functional programming and object-oriented programming.

I won’t go into such discussions, but some features, I think everyone would agree, are needed. You should be able to define higher-order functions, you sh

RStudio supports two version control systems, Subversion and git. Of these, git is the most widely used, and although these things are very subjective of course, I think tha
