Dynamic oscillogram
This graphical function displays a time wave as an windowed oscillogram.
dynoscillo(wave, f, channel = 1, wd = NULL, wl = NULL, wnb = NULL, title = TRUE, ...)
wave |
an R object. |
f |
sampling frequency of |
channel |
channel of the R object, by default left channel (1). |
wd |
a numerical vector, duration of the window (in seconds) |
wl |
a numerical vector, length of the window (in number of points). |
wnb |
a numerical vector, number of windows (no unit). |
title |
a logical, if |

The arguments wd, wl and wn have to be used isolated, not in conjunction. They basically do the same, ie they set the duration of the zooming window that is slided along the signal. For instance, for a 5 seconds sound with a sampling rate (f) at 44.1 kHz, wl = 4096 is equivalent to wd = 4096 / 44100 = 0.093 s and equivalent to wnb = 5*4096 / 44100 = 53.
This function requires the package rpanel.
