HowTo Install ShinySky Collection of Shiny UI Packages

Introducing ShinySky A collection of Shiny UI (User Interface) components/widgets that are not a part of standard Shiny. Currently there is only styled buttons and alerts in ShinySky, but the aim is to slowly add to it so that it becomes at “feature-parity” with Bootstrap, i.e. using standard R idiom, functions, one can completely define everything there is in Bootstrap. The intention is also to collate together the various components being customized. In this Article we are going to HowTo Install ShinySky Collection Shiny UI Packages Centos 7 / RHEL 7.
