ratings |
This is a data frame containing 3 columns or more. The first column contains subject numbers (there could be duplicates if a subject was assigned multiple ratings) and each of the remaining columns is associated with a particular rater and contains its numeric ratings. |
rho.zero |
This is an optional parameter that represents a vector containing an arbitrary number of null values between 0 and 1 for which a p-value will be calculated. If not specified then its defauklt value will be 0. |
This function returns a vector containing p-values associated with the null values specified in the parameter rho.zero.
