R help - May 2009 - Seewave options

Good afternoon, 

My name is Thiago. I'm?a graduate student?and affiliated to an Anuran
Bioacustic and Systematics Laboratory at UFU (Federal University of
Uberl?ndia)?in Brazil.?The professor in charge of the?lab (Dr. Ariovaldo Antonio
Giaretta) and I?have recently been?making use?of R, specially the packages Sound
and Seewave so as to analize?anuran recordings. This software is just fantastic,
but?I am writing?to ask for help about the graphics generated by Seewave. A
graphic and the?script I used?are attached?to the e-mail, so that you are able
to verify if it is possible to reduce the graphic scale of the Y-axis (see we
need only until 10 KHz, even less than it). The fact of recording at 44100 Hz/16
bits resolution?may be?a possible cause for such a long scale, but?that is
the?only way to record with the?best quality... If you?think it is easier to
change my script and send me back, I would reallly appreciate?it too.
I am looking forward to your reply.? 
Thanks beforehand,

See ?spectro and its "flim" argument:

spectro(x, wl = 256, grid = FALSE, osc = TRUE,
         listen = TRUE, flim = c(0, 10))
