description of commands and steps taken to create a version controlled shiny-server

link to blogpost

This is a mix of the excellent guide by Dean Attali and a setting up a webserver guide I found here. I mean hire that guy for your shiny jobs!

Today [2018-02-19] I found another example (a bit more advanced) of deployment from git

A version controlled shiny-server

The final version of this server has shiny-server installed and working and can be controlled from your own

Executes and plots collatz problem (AKA hotpo)
### Collatz problem hotpo problem (half or three plus one)
#https://en.wikipedia.org/wiki/Collatz_conjecture
#
#The Collatz conjecture is: This process will eventually reach the number 1,
#regardless of which positive integer is chosen initially.
#
#If the conjecture is false, it can only be because there is some starting
#number which gives rise to a sequence that does not contain 1. Such a sequence
#would either enter a repeating cycle that excludes 1, or increase without
#bound. No such sequence has been found.
