[R] densities from a list with data.frames

Hi there,

I have a list which consists of data frames (all data frames have the same 
amount and type of columns but different length).
Now, I'd like to calculate for each data frame in the list the density function 
of the values of the fist column ($V1).

This list could be an example:

l <- list( data.frame(rnorm(100)), data.frame(rnorm(20)), data.frame(rnorm(200)) )

Can anybody help? I'm sure there is a nice short way to do this :-)
