[R] list manipulation

[antonio rodriguez]

Hi,

Having a list, see below output of dput(), with 189 elements of variable 
length (I dput just the first element), I want to select, those values 
within a certain period, is to say:

lasker[[1]] elements for "1988-01-*"

Any idea?

Antonio

dput(lasker[1], control = "all")
