Widgets for Floating Point Number Ranges

An R6 class and a constructor function for the creation of widgets that can be used to manipulate floating pairs of point numbers that are bounded within an interval, where a pair defines a number range.

Usage

BoundedFloatRangeWidget(value, min, max, ...)

Arguments

value

A pair of floating point values.

min

The lower bound of the enclosing interval.

max

The upper bound of the enclosing interval.

...

Other arguments, passed to the superclass initializer.

Details

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