Airbnb Market Data

## This README is generated from README.Rmd

This is a simple visualization inspired by InsideAirbnb. Written in R, built on Shiny framework.

Demo can be found at - https://tmasjc.shinyapps.io/airbnb_market_data/

Motivation

This project aims to demonstrate

• reactivity of Shiny framework
• converting Rscript to a command line utility
• shipping Shiny data product with Docker

Any constructive feedback is greatly appreciated.

Download Data

This project ships with 2 cities data (Berlin and Vienna). You may use the command line tool, download_csv.R to import more data.

# Make sure it is executable
chmod +x download_csv.R
# Download data for Rome
./download_csv.R Rome

Of course, you can also download the data manually from InsideAirbnb. Navigate to your desire city section and download file named “listings.csv” (the summary version). Put your download into the Data/ folder.

Usage of Command Line Tool

Execute ./download_csv.R {city} to download desire {city} market data.

Use list instead of a city name to view all available cities.

# View all available cities
./download_csv.R list

 [1] amsterdam         antwerp           asheville         athens           
 [5] austin            barcelona         berlin            boston           
 [9] brussels          chicago           copenhagen        denver           
 ...

The utility automatically fetches the latest data available. If you prefer a particular snapshot, you may use -s {city} to list date indexes and specify particular -i <index> to download.

# First, see what's available for Vienna
./download_csv.R list -s vienna

|City   |Dates      |Index |
|:------|:----------|:-----|
|vienna |2017-09-15 |1     |
|vienna |2017-08-11 |2     |
|vienna |2017-07-10 |3     |
|vienna |2017-06-07 |4     |
|vienna |2017-05-09 |5     |
|vienna |2017-04-09 |6     |
|vienna |2017-03-08 |7     |
...

# Then, you may specify index to download
# i.e if you desire snapshot on 2017-03-08, choose 7
./download_csv.R vienna -i 7
