Plot the recurrence matrix.
1 2  recurrencePlot(takens = NULL, time.series, embedding.dim,
time.lag, radius)

time.series 
The original time series from which the phasespace reconstruction is performed. 
embedding.dim 
Integer denoting the dimension in which we shall embed the time.series. 
time.lag 
Integer denoting the number of time steps that will be use to construct the Takens' vectors. 
takens 
Instead of specifying the time.series, the embedding.dim and the time.lag, the user may specify directly the Takens' vectors. 
radius 
Maximum distance between two phasespace points to be considered a recurrence. 
WARNING: This function is computationally very expensive. Use with caution.
