As pointed out by a recent read the R source post on the R hub’s website, reading the actual code, not just the documentation is a great way to learn more about programming and implementation details. But there is one more activity to get even more hands-on experience and understanding of the code in practice.
In this post, we provide tips on how to interactively debug R code step-by-step and investigate the values of objects in the middle of function execution.
In this post we will look at yet another productivity increasing feature of the RStudio IDE - Code Snippets. Code Snippets let us easily insert and potentially execute predefined pieces of code and work not just for R code, but many other languages as well.
In this post we will cover 4 different ways to increase productivity using Code Snippets and provide 11 real-life examples of their use that you can take advantage of instantly.
Calling functions in R usually involves typing brackets. And since many of our actions in R involve calling a function, we will have to type a lot of brackets working with R. Often it would make our life a lot easier if we could omit the need to type brackets where convenient. We will do exactly that today.
Work in R faster with custom bracketless commands A good starting example is, well, quitting R altogether.
