Print the results of a chi-square test

1	print_association_text(data, x, y, var1_name, var2_name)

`x`	A contingency table (passed as `table` or `matrix`) or an object of type "htest" returned by `chisq.test`. Can also handle objects returned by `chisq.unif.test` from the `spgs` package.
`es`	Boolean. Should the phi coefficient be printed as a measure of effect size. See details.
`correct`	Boolean. Apply a continuity correction? See `chisq.test`. Only has an effect if the chi-square-test is computed by this function, i.e., if `x` is a contingency table. The default value is `FALSE`.
`decimals`	How many decimals should be printed
`decimals_p`	How many decimals should be printed for the p-value (defaults to 3)

The argument es only has an effect if x is passed as a 2x2 contingency table. In this case, the phi coefficient is computed as a measure of effect size (see Cohen, 1988, page 223).

A string describing the results of the chi-square test to be printed in Rmarkdown documents.

# Pass a matrix
x <- matrix(c(12, 5, 7, 7), ncol = 2)
print_chi2(x) # does not use continuity correction by default
print_chi2(x, correct = TRUE) # uses continuity correction

# Pass a table
tab <- table(rbinom(150, 1, 0.5), rbinom(150, 1, 0.1))
print_chi2(tab, correct = FALSE)

# Pass a chi-squared test object
print_chi2(chisq.test(tab, correct = FALSE))
