Plotly 1

Load the palmerpenguins data set and create a scatterplot of body_mass_g vs. flipper_length_mm from the penguins data set. Use color and shape to specify the species.

Once you have a static graphic you’re happy with, load plotly and convert it to an interactive graphic.

• What tools tips are included by default?
• Change the default tooltip to include “Species”
• (If time) use stringr so that the tooltip shows: “Species: Adelie” instead of just “Adelie”

Plotly 2

Create a bar chart of species from the penguins data set, then convert it to an interactive bar chart.

• What tools tips are included by default?
• What would you change?

Leaflet

• Find the names of the 3 islands in penguins
• Find appropriate lat/long locations for each of the islands in penguins using the internet
• Create a leaflet map with markers for each island (Tip: Start with the world map with no zoom)
• Include a popup with the island name

DT Table

• Create a {DT} table of the penguins dataset
• Add the option to filter, and make the font size 14pt

Putting it all together

new file –> rmarkdown –> from template –> flexdashboard (with bslib theme)

• Make all graphs plotly’s with appropriate tooltips
• Replace the data output with your {DT} datatable
• Include your leaflet map on a new page
• Add value boxes on the same page as your map that show the number of penguins that live on each island
• Change the theme of the dashboard
