R Documentation

Accessor method for the `PWMThreshold` slot in a `parameterOptions` object

Description

Accessor method for the PWMThreshold slot in a parameterOptions object

Usage

PWMThreshold(object)

Arguments

object

object is a parameterOptions object

Details

The computePWMScore function requires a so-called PWM Threshold. This threshold represents the Threshold at which PWM Score should be selected. The PWMThreshold is a positive numeric value (between 0 and 1. If set at 0, all sites will be selected. If set at 0.7 (Default value), then 70 % of PWM Score (and by extension binding sites) will be IGNORED. The top 30 % will be selected.

Value

Returns the value assinged to the PWMThreshold slot in a parameterOptions object
