Should add to PlackettLuce.Rd that mod$coefficients are the probabilities for each item that it is ranked first, given that first place is not tied. Then coef(mod) returns the log-probabilities, by default with the log-probability of the first item set to zero.
The model and the interpretation of its coefficients is now discussed in the vignette. This help file could probably still do with being updated though.
