The function evaluates the size of the objects formed from a dataset according to a statistic and returns the corresponding quantiles. Depending on the method the objects are simplices or ellipsoids.

x 
numeric; vector, dataframe or matrix. If 
probs 
numeric; vector of probabilities with values in [0,1]. Quantile orders of the statistic

character; the statistic used to measure the size of the objects. For 
method 
character; the type of (local) depth to be evaluated 
nsamp 
character or numeric; the number of objects that are considered. If 
size 
logical; if 
dimension 
numeric; only used with

arguments passed to 
When choosing between nsamp='all'
or a numeric value for nsamp
the value of choose(NROW(x), NCOL(x)+1)
must be considered to avoid very long computing times. When the number of possible objects is greater than the maximum vector length manageable by the machine, an error is returned by the system. In this case it is necessary to use the approximated procedure through the parameter nsamp
.
If size
is FALSE
then a vector with the quantiles is returned, otherwise a list with the following components:
quantile 
the requested quantiles 
stats 
the size of all objects
