spec-methods: Generic methods for objects with class 'spec'

Description

Generic methods for objects with class 'spec'

Usage

## S3 method for class 'spec':
as.list(x, ...)
as.spec(x, ...)
## S3 method for class 'amt':
as.spec(x, ...)
## S3 method for class 'spec':
lines(x, y = NULL, type = "l", ...)
## S3 method for class 'spec':
as.data.frame(x, ...)
data.frame.spec(x, ...)

Arguments

x

a 'spec' object

...

optional arguments

y

optional coordinate vector for the y-axis

type

character; the type of plot

Details

Objects with class 'spec' are simply lists with spectral estimates and parameters as.data.frame converts the list into a 'data.frame' with individual columns for the frequency, PSD, and taper vectors; all other information will be retained as an attribute.

Examples

#REX
library(psd)
