## Setter method for `chipSmooth` slot in `parameterOptions` object.

### Description

Setter method for `chipSmooth` slot in `parameterOptions` object.

### Usage

    chipSmooth(object) <- value

### Arguments

`object` | `object` is a `parameterOptions` object.
`value` | `value` is the positive numeric value to be assigned to the `chipSmooth` slot in `parameterOptions` Default value is 250 base pairs.

### Details

When computing ChIP-seq like (`computeChIPProfile`) profile from occupancy data (see `computeOccupancy`), the profiles are smoothed using a window of a given size. The default value is set at 250 base pairs.If `chipSmooth` is set to 0 then the profile will not be smoothed. We strongly encourage to set values when building a `parameterOptions` object.

### Value

Returns a `parameterOptions` object with an updated value for `chipSmooth` slot.
