Generic function for the computation of a risk for an IC.

The risk of an IC is computed.
object of class "InfluenceCurve"
object of class "RiskType"
.
object of class "Neighborhood"
; missing in the methods described here.
additional parameters to be passed to E
object of class "L2ParamFamily"
.
logical: should a call to checkIC
be done to
check accuracy (defaults to TRUE
; ignored
if nothing is computed but simply a slot is read out).
asymptotic covariance of IC
read off from corresp. Risks
slot.
asymptotic covariance of IC
under L2Fam
read off from corresp. Risks
slot.
asymptotic covariance of IC
read off from corresp. Risks
slot,
resp. if this is NULL
calculates it via getInfV
.

To make sure that the results are valid, it is recommended
to include an additional check of the IC properties of IC
using checkIC
