Chapter 48 18. Final assignment guidance

Create a new R Markdown document for your first exploratory data analysis file. Choose a clear file name, such as:

• EDA_01.Rmd
• CancerMortality_01.Rmd
• Assignment1.Rmd
• exploratory_analysis.Rmd

Your document should explain the data and cleaning process clearly enough for a colleague or manager to follow.

Include:

• a list of your datasets
• a function that can be applied to your dataset list using purrr
• a summary of dataset dimensions
• a description of what each column represents
• high-level statistics for each dataset
• missing value counts and how missing values were handled
• plots that help explain the data
• a clean section for population data cleaning and joining
• clear comments explaining what each major code block does and why
