plot.cepstrum: plots a cepstrum image in time - quefrency space
In landmarkacoustics/SoundPoints-R: an R version of the SoundPoints algorithm

Description Usage Arguments Value Author(s) See Also Examples

i'm still working with how to scale the amplitude values so that the image is meaningful.

1 2	## S3 method for class 'cepstrum' plot(x, pixel.colors = gray.colors(16, 1, 0), ...)

`x`	a cepstrum object
`pixel.colors`	a vector of color levels for the bitmap
`...`	other arguments for image

none

cepstrum image

##---- Should be DIRECTLY executable !! ----
##-- ==>  Define data, use random,
##--	or do  help(data=index)  for the standard data sets.

## The function is currently defined as
function (x, pixel.colors = gray.colors(16, 1, 0), ...) 
{
    if (is(x) == "cepstrum") {
        image(attr(x, "time"), attr(x, "quefrency"), x, col = pixel.colors, 
            xlab = "Time (s)", ylab = "Quefrency (Hz)", ...)
    }
  }
