Hi, I'm still confused about how to find out what methods are defined for a given class. For example, I know that
> today <- Sys.Date() will produce an object of type Date. But I'm not sure what I can do with Date objects or how I can find out. > ?Date refers me to the Date documentation page. But it doesn't tell me how, for example, to extract the current year from a date object. I tried > year(today)Error: could not find function "year" Is there some other function that does the job? I want a function f such that > f(today) will return 2011. Perhaps there is no such function. But in general I don't have any confidence that I would know how to find it if it existed or that I would know how to assure myself that there was no such function.
