Presentation Coursera, A random number generator

The assignement is to develop a app which is working on a host. In this case there is chosen for shinyapps as host. You can find it over here: https://samazzo.shinyapps.io/Projectrandomnumbers The criteria which it should be met are the following:

• Was there enough documentation on the shiny site for a user to get started using the application?
• the application run as described in the documentation?
• Was there some form of widget input (slider, textbox, radio buttons, checkbox, …) in either ui.R or a custom web page?
• Did server.R perform some calculations on the input in server.R?
• Was the server calculation displayed in the html page?
• Was the app substantively different than the very simple applications built in the class? N
• Here's your opportunity to give the app +1 for being well done, or neat, or even just a solid effort.

With the random number generator it is easy to get the number of random numers that you would like. In this app it is possible to pick from 0 to 1337 random numbers. That is the first step in the app. The second step is to pick an minimum and maximal value for the x axis. So you can select between a range from -1337 to 1337 to sample from. Simarly this works for the y-axis. With these two axis you can selct the area to sample your random numbers.

Ofcourse we used the library shiny to conduct this app. Secondary there where markdown and knitr.

I was facing some difficulties to insert a second button in the mainpanel (next to “random numbers”). Initially I had planned to put the aboutfile( with information about the used methods). This aboutfile is in RMD but unfortantly I couldn"t find a method to blend it in well. Locally is worked perfect :-)

library(markdown)
library(shiny)
library(knitr)

• The about file Can be found on https://github.com/Samazzo/Peer-graded-Assignment-Course-Project-Shiny-Application-and-Reproducible-Pitch (Although i did rather had it also under a button in the app :'())

• The readme file https://github.com/Samazzo/Peer-graded-Assignment-Course-Project-Shiny-Application-and-Reproducible-Pitch

• The shiny app, consisting in two parts:

• ui (userinterface)

• server (server)
