title: Insert charts to excel through xlsx package in R
body: <p>For a project I have been working on I make use of the package <code>xlsx</code> in <code>R</code> to create and design reports in Excel sheets. So far, any time I wanted to insert a scatter <code>plot</code>/<code>histogram</code>/<code>density plot</code> to my sheet I created a <code>ggplot2</code> object, saved it as an image and inserted it in to the sheet as an image.</p>
  
  <p>My question is, is there any way to add an excel chart to a sheet using the package <code>xlsx</code> (or any other <code>R</code> package). If, for instance, I have two columns and a scatter plot of one column against the second one, I would like the scatter plot to be an Excel chart such that changing the data in the columns manually would result in a change in the scatter plot. Any suggestions? </p>
