Leaflet browser fails to load scripts to display map

[alecGraves]

Hello, when using leaflet, I am running into a problem viewing results. When I run leaflet() from my R command line interface, the page in the browser display is blank (white), and several "Loading failed for the <script>" errors are displayed in the browser javascript console:

> leaflet()
