## S3 method for class 'decompSSA'
plot(x, by = "freq", normalize = FALSE, asFreq = TRUE,
      ann = TRUE, log = "xy", ...)

Arguments

x

Object of class decompSSA

by

How eigenvalues shall be ordered. "rank" denotes ordering by decreasing order."freq" denotes ordering by their frequency.

normalize

If eigenvalues shall be normalized to their sum.

asFreq

Only is applied if by="freq". Determines whether the frequencies shall be expressed as true “frequency” or be inverted as “period”.

ann

Whether to do annotation or not.

log

Use logarithmic axes, usage like log in par.

...

Other arguments to be passed to graphical functions.

Details

The SSA eigenspectrum is build of the (potentially normalised) eigenvalues ordered either by the dominant frequency of the corresponding eigenvector or by their rank (decreasingly order).
