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

Hello all,
I'll bet this is not complicated, but I really did hunt for information
on it, and tried some ideas without success.
Running Windows XP and R 2.3.1
I am using the Sound package to read in .wav files, and this works fine.
The R object produced is of class sample. I want to use some of the
functions in the package Seewave to do further analysis, but this
package wants data objects to be dataframes. So I tried various ways to
coerce samples to dataframes, but was not successful.
Does anyone have a hint/solution?
Thanks much,
