Bike Rental Shiny App

This application use the data collected from the Toronto Open Data to generate a histogram of the usage of rental bikes in Toronto during the month of June in 2020.

install.packages("opendatatoronto",
repos = "https://cran.us.r-project.org",
dependencies = TRUE)
library(opendatatoronto)
library(tidyverse)
library(lubridate)
library(shiny)

UI

There are two user inputs on the UI side:

• A slider that limits the maximum and minimum of the displayed values

• A checkbox that excludes users with a annual bike pass

 sidebarPanel(
sliderInput("dur",
"Trip Duration:",
min = 0,
max = 500,
value = c(0,500)),
checkboxInput("freq",
"Exclude annual users:",
value = FALSE))

Server

The following code is used for the server side logic, this includes downloading the data from the ‘opendatatoronto’ library.

 # get package
package <- show_package("7e876c24-177c-4605-9cef-e50dd74c617f")
# get all resources for this package
resources <- list_package_resources("7e876c24-177c-4605-9cef-e50dd74c617f")
# identify datastore resources; by default, Toronto Open Data sets datastore resource format to CSV for non-geospatial and GeoJSON for geospatial resources
datastore_resources <- filter(resources, tolower(format) %in% c('zip', 'geojson'))
# load the first datastore resource as a sample
data <- filter(datastore_resources, name == "Bike share ridership 2020") %>% get_resource()
data2 <- data$`2020-06.csv`
data2[grepl("Time",names(data2))] <-
lapply(data2[grepl("Time",names(data2))], parse_date_time, orders = "mdy HM")
data2$Dur <- as.numeric(data2$End.Time - data2$Start.Time,units="mins")

Application

The final application takes a while to load as the data needs to be downloaded and sorted through. In future iterations, I would save the data locally as an RDS file.
