Description
Plots the extremal coefficient evolution as the coordinates evolves.
Usage

Arguments
fitted 
A object of class " 
cov.mod 
A character string corresponding the the covariance
model in the maxstable representation. Must be one of "gauss" for
the Smith's model; or "whitmat", "cauchy" or "powexp" for
the WhittleMatern, the Cauchy and the Powered Exponential
covariance family with the Schlather's model. May be missing if

param 
Numeric vector of length 3. The parameters for the Smith's or Schlather model  i.e. c(cov11, cov12, cov22) or c(nugget, range, smooth). Please respect this order. 
n 
Numeric. 
xlab,ylab 
The xaxis and yaxis labels. May be missing. 
... 
Several options to be passed to the 
Value
A plot.
