Use tidyverse (ggplot2, dplyr) to explore the COVID-19 data for Louisiana.

We will work with two datasets.
The first [dataset](https://ldh.la.gov/Coronavirus/) is from Louisiana Department of Health where you can get three excel files for:

- Cases and Testing Data by Parish by Day

- Cases and Testing Data by Census Tract by Week

- Cases by Age/Gender by Week

The second [dataset](https://covidtracking.com/) is from the COVID Tracking Project where you can download two CSV files:

- Daily case count data ["louisiana-history.csv"](https://covidtracking.com/data/state/louisiana)

- Daily case data by race ["CRDT Data - CRDT.csv"](https://covidtracking.com/race/about#download-the-data)

<!-- https://covidtracking.com/data/state/louisiana -->

## Q1

Summarize following objects using appropriate graphs:

- Daily test counts by Parish

- Daily Negative test counts by Parish

- Daily Positive test counts by Parish

- Weekly total case count by Age group

- Weekly case count by Age group and Region

- Weekly total case count by Gender

- Weekly case count by Gender and Region

- Weekly case count by Gender and Parish

- Daily case count by Race group of **State LA**

- Daily death count by Race group of **State LA**

## Q2

Link the daily case count data from the two sources.  Summarize your findings.

## Q3

Recreate the 4 plots (New tests, New cases, Current hospitalizations, and New deaths) of total daily case counts with 7-day average of Full range at [the COVID tracking project website](https://covidtracking.com/data/state/louisiana)

## Q4

Compile a tibble that contains cumulative percent positivity of tests by Parish.

Plot the **cumulative** percent positivity of tests of Parish on a map for the weeks containing dates (one plot for each week):

- March 22, 2020 (stay at home order starts)

- May 15, 2020   (stay at home order lifted, phase 1 starts)

- June 5, 2020   (phase 2 starts)

- July 13, 2020  (Mask mandate)

- January 1, 2021 (New Year's eve within holiday season)

- January 10, 2021 (Peak of new cases across US)

## Q5

Plot new cases by lab collection date with a 7-day average line of New Orleans and Baton Rouge.

Explain your findings.
