Examples

# chi-squared test of independence for college completion
# status depending on one's self-identified income class
chisq_test(gss, college ~ finrela)

# chi-squared goodness of fit test on whether self-identified
# income class follows a uniform distribution
chisq_test(gss,
           response = finrela,
           p = c("far below average" = 1/6,
                 "below average" = 1/6,
                 "average" = 1/6,
                 "above average" = 1/6,
                 "far above average" = 1/6,
                 "DK" = 1/6))
