Assignments

1. Use the principles of data visualization introduced in week #2 to complete this week's assignment. The elements you are expected to consider are
   • a. Marks and channels: point shapes, size, colors, etc.
   • b. Legends and annotations (text and images): font size and face, colors, positions, etc.
   • c. Title and tick mark labels: font size and face, size, colors
2. The information of the data set
   • a. Foraging Penguin Size Data Set DATA SET.
   • a. Foraging Penguin Size Data Set Penguin Image.
   • b. Data Description DATA DESCRIPTION.
3. Steps for creating the visualization using the base plot functions
   • a. Download the penguins data set and then upload it to your Github data repository.
   • b. Find an image of a penguin and upload the image to the Github repository.
   • c. Read the data set to R from the Github data repository directly.
   • d. Open an R Markdown document. You are encouraged to use my template for all assignments.
   • e. Choose numerical variables (Bill_length_mm and Flipper_length_mm) from the penguins data set to make a scatter plot and color the points based on the species.
   • f. The point size should be proportional to body_mass_g of the corresponding penguin.
   • g. insert the image of the penguin you uploaded to the Github repository to the scatter plot.
   • h. add a legend to enhance the readability of your plot.
   • i. make sure the axes of your plot are appropriately labeled. The title of plot should reflect the content in the plot.
   • j. knit the RMD to HTML format and upload your HTML file to your Github repository.
4. Submission Requirements
   • a. URL of the HTML uploaded to your Github site.
   • b. Upload your RMD source file to D2L dropbox.
   • c. A late submission will receive penalty points (each assignment is worth 10 points).
5. D2L Submission Due: Wednesday, 11:30 PM Please submit your work through the D2L dropbox.
