WebCramer's V is used as a measure of association between two nominal variables, or as an effect size for a chi-square test of association. For a 2 x 2 table, the absolute value of the phi statistic is the same as Cramer's V. Because V is always positive, if type="perc" , the confidence interval will never cross zero.
