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, ______________________ Thiago Ribeiro de Carvalho Laborat?rio de Comportamento, Ecologia e Sistem?tica de Anuros Neotropicais Universidade Federal de Uberl?ndia http://lattes.cnpq.br/0618169962335506 Veja quais s?o os assuntos do momento no Yahoo! +Buscados http://br.maisbuscados.yahoo.com -------------- next part -------------- An embedded and charset-unspecified text was scrubbed...

See ?spectro and its "flim" argument:
spectro(x, wl = 256, grid = FALSE, osc = TRUE,
listen = TRUE, flim = c(0, 10))
