I would like to change the aspect ratio or figure size of a plot that gets printed within an R notebook in RStudio.
I'm able to adjust the aspect ratio with the fig.asp chunk argument. For example, in the minimal example below, the plot aspect ratio correctly becomes 2. However, at the same time, the plot also becomes very large, full width within the notebook (screenshot below). How can I change the aspect ratio without the plot becoming full width within my notebook? Specifying fig.width or out.width arguments doesn't make a difference.
Environment:
R version: 3.6.1 (2019-07-05)
RStudio version: 1.2.1541
platform x86_64-apple-darwin15.6.0
arch x86_64
os darwin15.6.0
system x86_64, darwin15.6.0
Minimal example:
---
title: "R Notebook"
output: html_notebook
---
This is an [R Markdown](http://rmarkdown.rstudio.com) Notebook. When you
execute code within the notebook, the results appear beneath the code.
Try executing this chunk by clicking the *Run* button within the chunk or
by placing your cursor inside it and pressing *Cmd+Shift+Enter*.
```{r, fig.asp=2, fig.width='200px'}
plot(cars)
```
