cghseg (version 1.0.5)

beta<-: Replace slot beta

Description

changes slot beta of a CGHoptions object

Arguments

.Object

an object of the CGHoptions class

Value

None

Details

CGHo["beta"] sets the proportion of each Kmax in multiKmax. If uniKmax[[i]] is the Kmax of profile i then $$\code{multiKmax} = \beta \times \sum_i \code{uniKmax[[i]]}$$ MultiKmax must be greater than the number of profiles, but should not be too small since it should be greater than the selected number of segments (unknown).
