default.param: default.param

In apomatix/AnalysisPageServer: A framework for sharing interactive data and plots from R through the web

Description

Build a default AnalysisPageParam for one argument

Usage

default.param(name, prototype, ...)

Arguments

name	Name of the parameter
prototype	Default value on which the parameter should be built.
...	Further arguments passed to the constructor for the appropriate parameter type. For example, you can include label, description, advanced and show.if.

Details

You provide the name of the argument and default and I build an AnalysisPageParam. The magic here is as follows:

1. Named lists become compound.param, with default.param() then called recursively.

2. Unnamed lists of become array.param, with default.param() called on the first element of the list to build the prototype. The length of the list is taken as the start value. min/max default to 0/Inf. (Advanced Note: the name is copied to the sub-element)

3. Vectors of length > 1 become select.params

4. Vectors of length 0 or 1 and NULLs become simple.params

On any other type of argument it throws an error.

Value

AnalysisPageParam
