CHC Snippets

Intro and Purpose

A code snippet is quick way to access code. For example, if you find yourself loading in the dplyr package on a daily basis, you could create snippet called dp that contains the code library(dplyr). Then you can type dp and hit “tab” and the library(dplyr) will appear. You can check what code snippets you have and edit them by going to “Tools” and selecting “Edit Code Snippets”. Along with reducing unnecessary typing, snippets are a great way to quickly access code that is easily forgotten. The dplyr syntax for applying a function across multiple columns can be tricky to remember and tedious to find. So we can make snippet, lets call it ac that contains across(COLS), ~ifelse(is.na(.x), 0, 1). So, when we type ac in the console or a code chunk and hit “tab”, across(COLS), ~ifelse(is.na(.x), 0, 1) will appear.

Snippets are not just for R code! You can have snippets for HTML, Quarto, JavaScript, etc.. Lets start with the R code snippets first.

R

snippet sc select(starts_with(““))

snippet ac across(COLS), ~ifelse(is.na(.x), 0, 1)

Quarto

Callout boxes

red important

snippet def :::{.callout-important} ### Definition ${1:text} ::: snippet redbox :::{.callout-important} #### Title text

:::

2 columns

snippet column :::: {.columns} ::: {.column width=“50%”} Left stuff ::: ::: {.column width=“50%”} Right stuff ::: ::::

panel tabset

snippet tabset ::: {.panel-tabset} ## header1

Tab content

## header2

Tab content
:::
