report_effectsize with chi2 object: Error in abs(r): non-numeric argument to mathematical function

[rempsyc]

It seems that chi2 htest objects should be supported by report_effectsize through .report_effectsize_chi2. However, that does not seem to be working as expected.

library(effectsize)
library(report)
packageVersion("report")
#> [1] '0.5.5.3'
M <- as.table(rbind(c(762, 327, 468), c(484, 239, 477)))
dimnames(M) <- list(gender = c("F", "M"), party = c("Democrat","Independent", "Republican"))
(x <- chisq.test(M)) 
#> 
#>  Pearson's Chi-squared test
#> 
#> data:  M
#> X-squared = 30.07, df = 2, p-value = 2.954e-07
effectsize(x)
#> Cramer's V (adj.) |       95% CI
#> --------------------------------
#> 0.10              | [0.07, 1.00]
#> 
#> - One-sided CIs: upper bound fixed at [1.00].

• chisq.test
• friedman.test

Similar idea with friedman.test:

library(report)
library(effectsize)
packageVersion("report")
#> [1] '0.5.5.3'

wb <- aggregate(warpbreaks$breaks,
                by = list(w = warpbreaks$wool,
                          t = warpbreaks$tension),
                FUN = mean)
wb
#>   w t        x
#> 1 A L 44.55556
#> 2 B L 28.22222
#> 3 A M 24.00000
#> 4 B M 28.77778
#> 5 A H 24.55556
#> 6 B H 18.77778
x <- friedman.test(wb$x, wb$w, wb$t)
effectsize(x)
#> Kendall's W |       95% CI
#> --------------------------
#> 0.11        | [0.11, 1.00]
#> 
#> - One-sided CIs: upper bound fixed at [1.00].

But maybe that's because there is no report_htest_friedman.R file or function.

[DominiqueMakowski]

isn't it related to the addition of CIs in effectsize()?

[strengejacke]

In report_effectsize.htest() we need to add if-statements for the above mentioned failing htests (Chi2 works meanwhile) and add methods for those (like in report_htest_wilcox.R).
