How to run

1. Run with pure RShinny on RStudio

   Clone the project to your dir. Open RStudio and set working dir to the project. Open the app.R file and click the Run App button top-right of the code editor panel or run runApp('<repository_dir>') in console.

2. Run with GitHub connection with RShinny on RStudio

   In RStudio, run the following codes and wait a few seconds while downloading.

# install.packages("RShiny")
library(RShiny)
runGitHub("nyc-yellow-taxi-vis", "Forrest-Li")

3. Run online in shinnyapps.io

   I already upload the app on the shinnyapps platform. If you want to save resource of your computer. You can take a look at the app here: https://forrestliyx.shinyapps.io/nyctaxivis/

Adjustment of attributes

The Time slicing mode will switch between mode 1 & 2, which means if you're in one mode, the other mode will be disabled.

Time in a day are differently specified between weekends and workdays.

In Time slicing mode 2, before checking View by hours box: after checking:

Current Deficiencies

• Ugly UI will be improved later.
• Coding structure is inefficient (it's actually a mess, a disaster), will be reconstructed.
• Only about 10% randomly data are selected, if efficiency will be improved, more data will be included.
