plot-FreqRep: Plot the values of the FreqRep.
Description
Creates a K x 2 plot depicting a
FreqRep object. Each of the K
``lines'' of subplots shows the frequency representation
for one value of $\tau$. The real and imaginary
part are shown on the left and the right, respectively.Usage
## S3 method for class 'FreqRep,ANY':
plot(x, ratio = 2, frequencies = 2 * pi *
  (1:(floor(length(x@Y)/2)))/length(x@Y), levels = x@levels)
Arguments
ratio
quotient of width over height of the
  subplots; use this parameter to produce landscape or
  portrait shaped plots.
frequencies
a set of frequencies for which the
  values are to be plotted.
levels
a set of levels for which the values are to
  be plotted.
Value
- Plots the 
FreqRep for all frequencies
and levels specified.
