cohen.d does not agree with other cohens_d measures #59

I'm an R newbie, so I'm probably missing something but the effsize package gives a radically different value for cohen's d from effectsize - which agrees with JAMOVI and hand calculation in excel.:

cohen.d(guilty$sel[guilty$Type == "probe"],guilty$sel[guilty$Type == "irrelevant"], paired = TRUE)

Cohen's d

d estimate: 0.3609801 (small) 95 percent confidence interval: lower upper 0.2174820 0.5044782

Whereas: from the effectsize package (and Jamovi) cohens_d(guilty$sel[guilty$Type == "probe"],guilty$sel[guilty$Type == "irrelevant"], paired = TRUE) Cohen's d | 95% CI

1.02 | [0.54, 1.49]
