Reading NYC Open Data on Emergency Visits

emergencyVisits =

fromJSON("https://data.cityofnewyork.us/resource/2nwg-uqyg.json?$limit=3000")

Examining the data, we see two dates: when the visit was actually made, and when the data was made available. We are interested in the former (the actual visits).

Question 1: Convert the dates to proper dates

Question 2: Get only the last 100 days

Create a dataframe that contains only the last 300 visits (sorted by the dates of actual visits)

Question 3: Are the ED Visits in a numerical format? If not, convert

Question 4: Calculate the number of visits per ZIP code.
