Motivation

This project aims to exercise

utilizing various reactivity features by Shiny

The utility automatially fetches the latest data available (of a city). If you prefer a particular time snapshot, you may use -m <city> to list date indexes and specify particular -i <index> to download.

# First, see what's available for Vienna
./getting_data.R list -m 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
./getting_data.R vienna -i 7
