View source: R/getCliffsD.R

Wrapper function to call effsize::cliff.delta. Returns only the Cliff's delta estimate and its confidence intervals. For further details on the original function or to use the original function, see effsize::cliff.delta. The magnitude is assessed using the thresholds provided in (Romano 2006), i.e. |d|<0.147 'negligible', |d|<0.33 'small', |d|<0.474 'medium', otherwise 'large' Minimum value is -1, maximum value is 1. Values closer to -1 indicate that the first group tends to endorse lower values than the second group. Values closer to 1 indicate that the first group tends to endorse higher values than the second group. Values closer to 0 indicate that the first group tends to endorse similar values as the second group.

1	getCliffsD(col, g, withCI = FALSE)

`col`	a numeric vector with data values, with complete cases
`g`	factor; a factor for a grouping variable. The first level is the group to which the second level is compared.
`withCI`	logical; include CIs?
