title: How to plot a list of plots in a grid
body: <p>At the moment I wish to plot multiple plots in the same window, using ggplot2. I've searched on the Internet and I found out that the <code>gridExtra::grid.arrange</code> function will do the job. </p>
  
  <p>For it to work, I have to include each plot in the argument as <code>gridExtra::grid.arrange(plot1,plot2,plot3,...,plotN)</code>. But, what if I would like to make a more generic use of this function and would like to enter a list of plots? <code>myList &lt;- list(plot1,plot2,...plotN)</code></p>
  
  <p>Inputing a list of plots and inputing in the form of <code>unlist(myList)</code> in the function gives an error. So, would would be the solution for this problem? </p>
