I'm not familiar with seewave package, but I imagine what you have to do is
extract the sound component of the sample object and convert that to a data
frame.

> waveLeft <- 2*((seq(0,80,length=88200)%%1^2)-.5)
> s <- as.Sample(waveLeft,44100,16)
> ds  <- data.frame(s$sound)
> is.data.frame(ds)
[1] TRUE
