Description

Setter method for the naturalLog slot in a parameterOptions object.

Usage

naturalLog(object)<- value

Arguments

object	object is a parameterOptions object.
value	value is a logical value that will determine if the natural log or log2 should be used for the computation of the Position Weight Matrix.

Details

During the computation of a Postion Weight Matrix, the Position Probability Matrix (derived from a Position Frequency Matrix) is log transformed. This parameter provides whcih "log transform" will be used. If TRUE, the Natural Log will bu used (ln). If FALSE, log2 will be used. We strongly encourage to set values when building a parameterOptions object.

Value

Returns parameterOptions object with an updated value for the naturalLog slot.
