Setter Method for the `lambdaPWM` slot in a `parameterOptions` object

Description

Setter Method for the lambdaPWM slot in a parameterOptions object

Usage

lambdaPWM(object)<-value

Arguments

`object`	`object` is `parameterOptions` object
`value`	`value` is the numeric value to be assigned to the lambdaPWM slot. Default set at 1.

Details

The model underlying ChIPanalyser internally infers two paramters: number of bound molecules and lambda. Lambda represents a scaling factor for the Position weight matrix (PWM). This can be described as how well does a TF discriminate between high affinity and very high affinity sites.

Value

Returns the value assigned to the lambdaPWM slot in a parameterOptions object.
