Arguments
data 
array of univariate or multivariate series with dimension T*N.samples*d. T: number of time steps of each sample, N.samples: number of realisations of the same stationary process, d: dimension. 
u 
sequence of levels to be considered 
lty 
type of line 
col 
color of line 
add 
if add=TRUE lines is added to current plot 
CI 
if CI=TRUE a fluctuation interval at 1alpha level of confidence is computed and plotted 
alpha 
confidence level 
N.s.data 

xlab 
a title for the x axis 
ylab 
a title for the y axis 
ylim 
numeric vectors of length 2, giving the y coordinates ranges. 
Value
list including
u 
sequence of levels 
F 
empirical cdf: P(data<u) 
Nu 
number of upcrossings 
CI. 
fluctuation interval
