R help - Apr 2008 - aggregateSeries and seriesData in R?

hi to all!

(Q1):   I'd like to ask where can i find aggregateSeries and seriesData in R
packages?

(Q2):   how can i perform these Splus commads in R?

    e.g.   annualMax.sp500 =
aggregateSeries(-spto87,by="years",FUN=max)
              hist(seriesData(annualMax.sp500))


(Q3):   is the method of probability-weighted moments available in evir package?

Thanks!

Filame
