Developing Data Products Course Project: Shiny Application and Reproducible Pitch

Application Overview

This is BMTC (Bangalore Metropolitan Transport Corporation) route map presentation. This application helps to draw a route map of bmtc route numbers.

How it works?

• This application written in Shiny which is a web application framework for R
• The source code contains two files: ui.R and server.R
• ui.R define UI for application that draws a bmtc route map
• server.R define server logic required to draw a bmtc route map
• This application leverages BMTC Route Data and leaflet for displaying the route map
• The application is hosted on Rstudio’s Shiny server in the cloud (Shinyapps.io)

Slide with Code/Output

library(leaflet)
#library(dplyr)
bmtc_routes <- read.csv("bmtc_routes.csv", stringsAsFactors = FALSE)
bmtc_300A <- bmtc_routes[bmtc_routes$route_no == "300A",]
bmtc_300A_route_map <- leaflet() %>%
      addTiles()
bmtc_300A_route_map <- bmtc_300A_route_map %>%
      addMarkers(
            lat = as.numeric(bmtc_300A[3][[1]]),
            lng = as.numeric(bmtc_300A[4][[1]]),
            popup = as.character(bmtc_300A[2][[1]])
      )
bmtc_300A_route_map
