Hi Sam,
Try this:

library(hints) # may need install.packages("hints") first
fm1 <- lmer(Reaction ~ Days + (Days|Subject), sleepstudy)

This might lead you to something like

fm1 <- lmer(Reaction ~ Days + (Days|Subject), sleepstudy)

fm1.results <- list(ran=ranef(fm1), fix=fixef(fm1), vc=VarCorr(fm1))

Also see
?"mer-class" for a complete list of methods for mer objects.
