title: Correlation plot between two variables with line and person r value in graph - seeking alternate example
body: <p>Would just like some clarity here and a different example if someone has one.
  Initially I wanted to use this example because it has the graph, the mean line, and the r value all presented in the graph: <a href="http://www.sthda.com/english/wiki/correlation-test-between-two-variables-in-r" rel="nofollow noreferrer">http://www.sthda.com/english/wiki/correlation-test-between-two-variables-in-r</a></p>
  <p>However, I'm using r studio server and creating a shiny app.
  Library ggpubr will simply not install.
  I've tried several ways to get this library to install.</p>
  <p>So, does anyone have an alternate example that might work?</p>
  <p>Cheers ~!</p>
