## 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.
