The RMediation applications are undergoing construction. We are sorry for any inconvience this may have caused. However, you can now access the RMediation page, as before, using the URL http://amp.gatech.edu/RMediation. For now, the links on the RMediation page will provide you with the appropriate applications until we post them back to the website.
We've updated the RMediation package to produce the graph of the distribution of the mediated effect with the overlayed plot of the confidence interval. You can save a copy of the graph by right clicking the graph, and then clicking "Save Image as...." (on Firefox) or "Save Picture as..." (on Internet Explorer).
