A function to detect participants that consistently respond exceptionally.
exceptionalScores(dat, items = NULL, exception = 0.025, totalOnly = TRUE, append = TRUE, both = TRUE, silent = FALSE, suffix = "_isExceptional", totalVarName = "exceptionalScores")
| dat | The dataframe containing the variables to inspect, or the vector to inspect
(but for vectors, |
|---|---|
| items | The names of the variables to inspect. |
| exception | When an item will be considered exceptional, passed on as |
| totalOnly | Whether to return only the number of exceptional scores for each row in the dataframe, or for each inspected item, which values are exceptional. |
| append | Whether to return the supplied dataframe with the new variable(s) appended (if TRUE), or whether to only return the new variable(s) (if FALSE). |
| both | Whether to look for both low and high exceptional scores (TRUE) or not (FALSE;
see |
| silent | Can be used to suppress messages. |
| suffix | If not returning the total number of exceptional values, for each inspected variable, a new variable is returned indicating which values are exceptional. The text string is appended to each original variable name to create the new variable names. |
| totalVarName | If returning only the total number of exceptional values, and appending these to the provided dataset, this text string is used as variable name. |
Either a vector containing the number of exceptional values, a dataset containing, for each inspected variable, which values are exceptional, or the provided dataset where either the total or the exceptional values for each variable are appended.
