You will implement the shiny app shown in Chapter 5 in Mastering Shiny by Hadley Wickham.
Task 1: app-1.R
Create a Shiny app based on 5.4. Call this file app-1.R.
To download, the files. This will put the files into a folder names ‘neiss’.
download.file("https://github.com/hadley/mastering-shiny/raw/master/neiss/injuries.tsv.gz", "neiss/injuries.tsv.gz") download.file("https://github.com/hadley/mastering-shiny/raw/master/neiss/products.tsv", "neiss/products.tsv") download.file("https://github.com/hadley/mastering-shiny/raw/master/neiss/population.tsv", "neiss/population.tsv")
app-1.R should create this app:
Task 2: app-2.R
Using app-1.R as a template/base, create a new file call app-2.R that starts with app-1.R.
Follow the instructions in 5.5 Polish tables.
app-2.R should look like this:
Task 3: app-3.R
Follow 5.6 Rate vs count to create app-3.R.
app-3.R should look like this:
Task 4: app-4.R
Follow 5.7 Narrative and create app-4.R.
app-4.R should looks like this:
Task 5: Make an Improvement
Create an enhancement on app-4.R and save it as app-5.R.
You can choose anything. A new layout, new shiny theme, add in a better ggplot2 theme.
More creative choices will get more credit.
Task 6: Zip your folder and load to Canvas
Save your folder as lastname-problem-set-04.zip.
It should have your data and be fully reproducible. You do not need to deploy your app to shinyapps.io.
