Theme: Making a Shiny app

Assignment Overview

Shiny is an R package that makes it easy for us to build interactive web applications using R. It is available on CRAN and can be installed using:

install.packages("shiny")

Shiny's awesomeness can help us:

• Host standalone apps on a webpage or embed them in R Markdown documents or build dashboards
• embed CSS themes, htmlwidgets, and JavaScript actions within Shiny apps for flexibility
• develop highly interactive apps and output changes as users modify inputs, without requiring a reload of the browser
• tap into Shiny's very attractive user interfaces (based on Twitter Bootstrap) and the customizable slider widgets with support animations
• enjoy the super fast data transfer between a browser and R
• tap into the reactive programming model that helps us focus on the key application code without worrying about background subroutines and lots of code.
• develop interfaces for our R packages
• and lastly, build websites

The Developed Shiny App

The developed Shiny app is a supplementary implementation to Dean Attalis’s BC Liquor app

As a key deliverable for this assignment, the developed Shiny app is hosted at shinyapps.io and can be assessed through this link.

Some of the key features added to the BC Liquor app:

1. **Image inclusion ** of the BC Liquor Store. Out of preference, this was added to my dashboardSidebar.
2. Inclusion of an interactive table using DT::renderDataTable() from the DT package. Included was also a caption, title, a table style, change in text and column header colours, a specification of pageLength e.t.c.
3. Inclusion of a download button to allow users download the results.
4. Inclusion of a additional plot parameters. Here I implemented the colourpicker package to select plot colors
5. Inclusion of dropdownMenus, icons and messages
6. Inclusion of tabBox() and tabpanel() to have plots in different box tabs.
7. Inclusion of CSS defined styles
8. The usage of shinydashboard and most of its features skins. Themes were tested using shinythemes::themeSelector()

Please visit the app for the implementation of more awesome features.
