rmoffset {seewave} | R Documentation |
This function removes the offset of a time wave.
rmoffset(wave, f, plot = FALSE, output = "matrix", ...)
wave |
an R object. |
f |
sampling frequency of wave (in Hz). Does not need to be specified if embedded in wave . |
plot |
logical, if TRUE returns an oscillographic plot of the wave
after removing the offset (by default FALSE ). |
output |
character string, the class of the object to return, either
"matrix" , "Wave" , "Sample" , "audioSample" or "ts" . |
... |
other oscillo graphical parameters. |
If plot
is FALSE
, a new wave is returned. The class
of the returned object is set with the argument output
.
