| rmoffset {seewave} | R Documentation |
This function removes the offset of a time wave.
rmoffset(wave, f, plot = FALSE, ...)
wave |
a vector, a matrix (first column),
an object of class ts, Sample (left channel),
or Wave (left channel). |
f |
sampling frequency of wave (in Hz).
Does not need to be specified if wave is an object of class ts,
Sample, or Wave. |
plot |
logical, if TRUE returns an oscillographic plot of the wave
after removing the offset (by default FALSE). |
... |
other oscillo graphical parameters. |
If plot is FALSE, rmoffset returns a one-column matrix
describing the new wave with the same sampling frequency as the original wave.
