Hello, I'm very new to R and have a problem to find the call rates of a specific category in a row in the following database:
resume <- read.csv('https://raw.githubusercontent.com/umbertomig/intro-prob-stat-FGV/master/datasets/resume.csv')
head(resume)
How can I find the call rate for a specific category such as "white" and "black" in the "race" row?
