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.
Thanks.
