Determining effect size

data

df <- data.frame(control = c(13698, 7319, 2421), test = c(4697, 9577, 50357))

run cramerV

rcompanion::cramerV(as.matrix(df), verbose = TRUE)

output

        Rows          = 3
        Columns       = 2
        N             = 88070
        Chi-squared   = 37090
        Phi           = 0.4212
        Corrected Phi = NA
        V             = 0.649
        Corrected V   = NA

        Cramer V 
           0.649

find the sum of control and test

13698+7319+2421+4697+9577+50357 #88069

why is N (88070) of the output not equal to 88069?

Hi, this is a read only mirror of CRAN, please see the package authors in the DESCRIPTION file. Look for Maintainer, BugReports and URL. Thanks!

All the output is rounded to the significant figures specified in the digits= option. Perhaps it shouldn't round the N. I'll change this.
