getModifyIC

Generic Function for the Computation of Functions for Slot modifyIC

Description

These function is used by internal computations and is rarely called directly.

Usage

getModifyIC(L2FamIC, neighbor, risk,...)
## S4 method for signature 'L2ParamFamily,Neighborhood,asRisk'
getModifyIC(L2FamIC,
          neighbor, risk, ...)
## S4 method for signature 'L2LocationFamily,UncondNeighborhood,asGRisk'
getModifyIC(L2FamIC,
          neighbor, risk, ...)
## S4 method for signature 'L2LocationFamily,UncondNeighborhood,fiUnOvShoot'
getModifyIC(L2FamIC,
          neighbor, risk, ...)
## S4 method for signature 'L2ScaleFamily,UncondNeighborhood,asGRisk'
getModifyIC(L2FamIC,
          neighbor, risk, ..., modifyICwarn = NULL)
## S4 method for signature 'L2LocationScaleFamily,UncondNeighborhood,asGRisk'
getModifyIC(L2FamIC,
          neighbor, risk, ..., modifyICwarn = NULL)

scaleUpdateIC(neighbor,...)
## S4 method for signature 'UncondNeighborhood'
scaleUpdateIC(neighbor, sdneu, sdalt, IC)
## S4 method for signature 'ContNeighborhood'
scaleUpdateIC(neighbor, sdneu, sdalt, IC)
## S4 method for signature 'TotalVarNeighborhood'
scaleUpdateIC(neighbor, sdneu, sdalt, IC)

Arguments

`L2FamIC`	object of class `L2ParamFamily`.
`neighbor`	object of class `"Neighborhood"`.
`risk`	object of class `"RiskType"`
`...`	further arguments to be passed over to `optIC`.
`sdneu`	positive numeric of length one; the new scale.
`sdalt`	positive numeric of length one; the new scale.
`IC`	a Hampel-IC to be updated.
`modifyICwarn`	logical: should a (warning) information be added if `modifyIC` is applied and hence some optimality information could no longer be valid? Defaults to `NULL` in which case this value is taken from `RobAStBaseOptions`.

Details

This function is used for internal computations. By setting RobAStBaseOption("all.verbose" = TRUE) somewhere globally, the generated function modifyIC will generate calls to optIC with argument verbose=TRUE.

Value

getmodifyIC: Function for slot modifyIC of ICs
scaleUpdateIC: a list to be digested in corresponding methods of getmodifyIC by generateIC
