Useful code chunk settings

``` {{r}}
#| message: false
#| warning: false
#| eval: false
#| echo: false
#| include: false
```

• message: false prevents messages from appearing in knitted doc
• warning: false prevents warnings from appearing in knitted doc

• eval: false includes the code chunk in the knitted document but prevents the code chunk from being run
• echo: false prevents code itself from printing but includes the results of the code
• include: false prevents code and its results from printing but still runs the code when knitted
