I am trying to figure out what the right parameter in the hist function in R does. The documentation is unfortunately unclear to someone without a deep understanding of statistics such as myself. 

The documentation as [stated online](http://www.stat.ucl.ac.be/ISdidactique/Rhelp/library/base/html/hist.html) is:

> 
> right logical; if TRUE, the histograms cells are right-closed (left open) intervals.
> 
> 
> 

What does it mean to be right-closed (or left open) intervals?
