This function will create a control object CovControlSest
containing the control parameters for CovSest
1 2  CovControlSest(bdp = 0.5, arp = 0.1, eps = 1e5, maxiter = 120,
nsamp = 500, seed = NULL, trace = FALSE, tolSolve = 1e14, method= "sfast")

bdp 
a numeric value specifying the required
breakdown point. Allowed values are between

arp 
a numeric value specifying the asympthotic
rejection point (for the Rocke type S estimates),
i.e. the fraction of points receiving zero
weight (see Rocke (1996)). Default is 
eps 
a numeric value specifying the
relative precision of the solution of the Sestimate (bisquare and Rocke type).
Defaults to 
maxiter 
maximum number of iterations allowed in the computation of the Sestimate (bisquare and Rocke type). Defaults to 120. 
nsamp 
the number of random subsets considered. Default is 
seed 
starting value for random generator. Default is 
trace 
whether to print intermediate results. Default is 
tolSolve 
numeric tolerance to be used for inversion
( 
method 
Which algorithm to use: 'sfast'=FASTS or 'surreal'=SURREAL 
A CovControlSest
object.
