## Setter Method for the `stepSize` slot in a `parameterOptions`

### Description

Setter Method for the `stepSize` slot in a `parameterOptions`

### Usage

    stepSize(object) <- value

### Arguments

`object` | `object` is a `parameterOptions` object
`value` | `value` is a positive numeric value that will be assigned to the `stepSize` slot in a `parameterOptions` object. Default is set at 10 base pairs.

### Details

It possible to restrict the size of the ChIP-seq-like profile produced by `computeChIPProfile`. Instead of returning ChIP-seq like score for each base pair, it is possible to skip base pairs and only return the predicted enrichement score for every "n" base pair (n is the value assigned to stepSize). This will reduce the size of the output data (unless step size is very large, this will not affect the accuracy of the model). Default is set at 10 base pairs.

### Value

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