array.param {AnalysisPageServer} | R Documentation

## array.param

### Description

Create an Array AnalysisPageParam

### Usage

    array.param(..., prototype, start = 1, min = 0, max = Inf)

### Arguments

`...` | Passed through to `simple.param`. This includes at least "name", optionally "label" and "description". but not "type" (which is set to "array") or "value" (which is set to empty string, but ignored anyway, since the prototype parameter will have its own value).
`prototype` | A single AnalysisPageParam that is the prototype for each of the elements in the array. Note that while only one param is allowed, it could potentially be either a compound or another array parameter.
`start` | The starting length of the array that should be rendered
`min` | The minimum allowed length of the array. Buttons to remove elements should be de-activated below this level (default 0).
`max` | The maximum allowed length of the array. Buttons to add elements should be de-activated above this level (default Inf).

### Details

An array AnalysisPageParam is a way of having a single parameter with multiple repetitions of some other (fixed) parameter type. The starting length, as well as minimum and maximum allowable lengths, are provided. If min != max then the front end should render some widget to add/remove elements.

By combining with `compound.param` a fairly complex data structure can now be specified.

### Value

AnalysisPageParam of type "array"

      one.gene <- simple.param(name="gene", label="Gene Symbol")
