These functions compute percentile ranks and cumulative frequencies for a
univariate distribution, and percentile ranks from one univariate
distribution (`x`

) corresponding to score values in another (`y`

).

A vector is returned containing either percentile ranks or
cumulative frequencies with length equal to `length(x)`

.
