You started learning the Statistics/Analysis focused language R and you want to do more. You want to build apps with it and host them on the Internet. All this is possible using Shiny.
Go to this site (https://shiny.rstudio.com/) directly and learn more.
If you have R Studio you have Shiny because Shiny is a package that you can download.
In this first part we only talk about the very basics.
I assume you have read my previous hands-on R examples in my blogs.
Here I just show a very basic (aka Hello World) example of creating content for a web page using R GUI. More will come later in my blogs.
Launch R Gui as shown and provide reference to the shiny "library" as shown by typing in the three lines of code (The four lines of code in red).
When you hit Enter after the third line where you define the shiny app, a browser window will open as shown displaying the apps output as shown at a port of the local host.
You also get a response (the last line) in the R GUI as shown.
That is all there is to create a content.
The ui summarizes your user interface, the server is something like a web serve rand shinyApp is your web response. No fuss, very simple.
