title: R - Changing ggplot plot size in jupyter
body: <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>
