I am just starting to use Quatro in the latest version of Rstudio. However, I'm very annoyed by the amount of space added between the command and the output in the R code chunk (rendered as pdf)
```{r}
3 + 1
```
You can add options to executable code like this
```{r}
#| echo: false
2 * 2
```
The `echo: false` option disables the printing of code (only output is displayed).
I am unable to find any references or global code chunk options to reduce this spacing. What is the usual R Markdown code chunk option for this?
