Description

Basic functions for weyl objects

Arguments

A weyl or spray object

val, d

Details

Function weyl() is the formal creator method; is.weyl() tests for weyl objects and is.ok.weyl() checks for well-formed sprays. Function as.weyl() tries (but not very hard) to infer what the user intended and return the right thing.

To create a spray object to pass to weyl(), use function spray(), which is a synonym for spray::spray().

Value

Return a weyl or a Boolean
