![]() What are code snippets?Ĭode snippets are pieces of re-usable boilerplate code. This part of our RStudio shortcuts and tips article teaches you everything you need to know. Tired of writing the same chunks of code over and over and having to remember all of the brackets and required parameters for functions? A good way to avoid it is by using code snippets. We find it to be easier to remember as an extension of the magrittr operator shortcut, so Pipe + Alt. Yes, the shortcut is long, but it can be helpful. It selects all occurrences in scope, you will have to just type a new name. It’s achieved by selecting the function or variable we want to change and pressing Ctrl + Shift + Alt + M. If you have to change a variable name in multiple places but you are afraid that “find and replace” will mess up your code, fear not. There is also a similar shortcut for a variable extraction available with Ctrl + Alt + V. You only need to provide the function name, all necessary inputs will be filled in automatically. Select it and press Ctrl + Alt + X – a shortcut for “extract into function”. If you have a statement that you want to convert into a function, don’t start from scratch. These are used for code externalization with knitr:read_chunk() function.
