Widgets for Bounded Floating Point Numbers

An R6 class and a constructor function for the creation of widgets that can be used to manipulate floating point numbers that are bounded within an interval

Usage

BoundedFloatWidget(value, min, max, ...)

Arguments

value

The floating point value

min

The lower bound of the interval

max

The upper bound of the interval

...

Other arguments, passed to the superclass initializer

Details

The function BoundedFloatWidget creates objects of the R6 Class "BoundedFloatWidgetClass", which in turn have the S3 class attribute "BoundedFloatWidget"

Public fields

value
