Autocorrelation of a spectrum. Generally, a high autocorrelation is associated with high signal, while white noise is not autocorrelated.
spectral_ac(x, lag = 1, colname = "spectral_ac")
| x | a hyperSpec object. |
|---|---|
| lag | lag at which the autocorrelation is calculated. |
| colname | name of the data column to be added to |
a hyperSpec object such as given for x with an additional
column in x@data.
