Adjust plot scale in R markdown

Question

How do I change the scale of a plot in R markdown? In other words, how do I make the output look more like to the plot on the bottom when I knit my HTML document?

---
title: "Test"
output: html_document
---

```{r}
data <- data.frame(x = 1:10, y = rnorm(10))
ggplot(data, aes(x, y)) +
    geom_point(size = 4)

Answer 1

For each code chunk in the curly braces at top you can set fig.height and fig.width which sets the output dimensions when knitting.
