[R] column of a list

I have a list of (same type) lists. I want to retrieve the same
entries of all my objects in the outer list.
eg:
a<-list("2006-01-23"=list(r=5,s=c(7,12,12,11,4)),
"2006-01-24"=list(r=6,s=c(3,8,8,9,12)))
a[][["s"]]

gives NULL, but I am looking for all the s-vectors in order to plot
and compare them (e changes to f in a day).
