R - Changing ggplot plot size in jupyter : <p>Using R in a jupyter notebook, first I set the plot size universally. Second, I would like to plot one single plot with a different size.</p>

<pre><code>## load ggplot2 library
library("ggplot2")
## set universal plot size:
options(repr.plot.width=6, repr.plot.height=4)

## plot figure. This figure will be 6 X 4
ggplot(iris, aes(x = Sepal.Length, y= Sepal.Width))   +  geom_point() 

## plot another figure. This figure I would like to be 10X8
ggplot(iris, aes(x = Sepal.Length, y= Sepal.Width))   +  geom_point() + HOW DO i CHANGE THE SIZE?
</code></pre>

<p>As you can see, I would like to change the second plot (and only the second plot) to be a 10X8. How do I do this?</p>

<p>Sorry for a potentially dumb question, as plot sizing is typically not an issue in Rstudio.</p>
