rmoffset: Remove the offset of a time wave

Description

This function removes the offset of a time wave.

Usage

rmoffset(wave, f, plot = FALSE, ...)

Arguments

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.

Value

• If plot is FALSE, rmoffset returns a one-column matrix describing the new wave with the same sampling frequency as the original wave.

Examples

data(tico)
# artifically generates an offset
tico2<-tico+0.1
# see the wave with an offset
oscillo(tico2,f=22050)
# remove the offset
rmoffset(tico2,f=22050,plot=TRUE)
