Calculating distance between categorical variables

In this exercise you will explore how to calculate binary (Jaccard) distances. In order to calculate distances we will first have to dummify our categories using the dummy.data.frame() from the library dummies

You will use a small collection of survey observations stored in the data frame job_survey with the following columns:

job_satisfaction Possible options: "Hi", "Mid", "Low"
is_happy Possible options: "Yes", "No"

Create a dummified data frame dummy_survey
Generate a Jaccard distance matrix for the dummified survey data dist_survey using the dist() function using the parameter method = 'binary'
Print the original data and the distance matrix
- Note the observations with a distance of 0 in the original data (1, 2, and 4)
