chisq_pval: P-value of chi-squared contingency table test

In angeloSdP/reportingTools: Tools for building report tables containing overall and per group summary statistics

P-value of chi-squared contingency table test

Description

P-value of chi-squared contingency table test

Usage

chisq_pval(y, g, pvdigits = 4)

Arguments

y	A numeric vector (or factor). Row variable in contingency table.
g	A numeric vector (or factor). Column variable in contingency table.
pvdigits	number of digits for the p-value

Details

If conditions for the validity of chi squared test are not met (expected frequencies less than 5) a Fisher exact test is performed instead.

Value

p-value of the chi squared contingency table test chisq.test(table(y,g))

Examples

df <- data.frame(g=rbinom(100,4,0.5),y=rnorm(sample(c(1:2),100,replace=TRUE)))
chisq_pval(df$y,df$g,pvdigits=3)
