Description

changes slot alpha of a CGHoptions object

Arguments

.Object

an object of the CGHoptions class

Details

CGHo["alpha"] sets the proportion of length of each profile that will be used for . If ni is the length of profile i then

\code{uniKmax[[i]]} = α n_i

The speed of execution of the method decreases with Kmax. Each Kmax must fulfill some conditions wrt CGHo:

\code{uniKmax[[i]]} > \code{nblevels}

\code{uniKmax[[i]]}< n_i
