Currently help(package = S4) looks like: coef-methods Methods for Function 'coef' in Package 'stats4' confint-methods Methods for Function 'confint' in Package 'stats4' logLik-methods Methods for Function 'logLik' in Package 'stats4' mle Maximum Likelihood Estimation mle-class Class '"mle"' for Results of Maximum Likelihood Estimation I think it would be more useful if it looked like: methods?coef Methods for Function 'coef' in Package 'stats4' methods?confint Methods for Function 'confint' in Package 'stats4' methods?logLik Methods for Function 'logLik' in Package 'stats4' ?mle Maximum Likelihood Estimation class?mle Class '"mle"' for Results of Maximum Likelihood Estimation And similarly help(package = base) could have ?":" Colon Operator ?"::" Double Colon and Triple Colon Operators ?"@" Extract Slots ?Arithmetic Arithmetic Operators That would make help just a little bit easier to use for the newcomer.
