audio 
a list returned by 
windowLength 
the length of each frame analyzed separately (ms) 
step 
time step between consecutive frames (ms) 
timeLag 
time lag between the original and timeshifted version of each
frame that together represent the phase portrait (ms). Defaults to the
number of steps beyond which the mutual information function reaches its
minimum or, if that fails, the steps until mutual information experiences
the first exponential decay  see 
theilerWindow 
time lag between two points that are considered locally
independent and can be treated as neighbors in the reconstructed phase
space. defaults to the first minimum or, if unavailable, the first zero of
the autocorrelation function (or, failing that, to 
nonlinStats 
nonlinear statistics to report: "ed" = the optimal number of embedding dimensions, "d2" = correlation dimension D2, "ml" = maximum Lyapunov exponent, "sur" = the results of surrogate data testing for stochasticity. These are calculated using the functionality of the package nonlinearTseries, which is seriously slow, so the default is just to get the phasegram itself 
pars_ed 
a list of control parameters passed to

pars_d2 
a list of control parameters passed to

pars_ml 
a list of control parameters passed to

pars_sur 
a list of control parameters passed to

bw 
standard deviation of the smoothing kernel, as in

bins 
the number of bins along the Y axis after rasterizing (has no
effect if 
plot 
should a spectrogram be plotted? TRUE / FALSE 
rasterize 
if FALSE, only plots and returns Poincare sections on the original scale (most graphical parameters will then have no effect); if TRUE, rasterizes the phasegram matrix and plots it with more graphical parameters 
colorTheme 
black and white ('bw'), as in seewave package ('seewave'),
or any palette from 
col 
actual colors, eg rev(rainbow(100))  see ?hcl.colors for colors in base R (overrides colorTheme)
