oscilloST: Show a stereo time wave as oscillograms

Description

This graphical function displays a stereo (2 channels) time wave as an oscillogram in a two-frame plot. The envelope of the wave can also be shown.

Usage

oscilloST(wave1, wave2 = NULL, f, from = NULL, to = NULL,
identify = FALSE, plot = TRUE, colwave1 = "black",
colwave2 = "blue", coltitle = "black",
collab = "black", cexlab = 1, fontlab = 1, colaxis = "black",
cexaxis = 1, coly01 = "grey47", coly02 = "black", title = FALSE,
bty = "l")

Value

• Data are returned as two-column matrix if plot is FALSE. identify returns a numeric object with the time coordinate of points successively chosen on the bottom oscillogram.
