The algebra and weyl objects

Description

Basic functions for weyl objects

Usage

weyl(M)
is.weyl(M)
as.weyl(val,d)
is.ok.weyl(M)

Arguments

M	A weyl or spray object
val, d	Value and dimension for weyl object

Details

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

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.

Value

Return a weyl or a Boolean

Examples

(W <- spray(matrix(1:36,6,6),1:6))
weyl(W)

as.weyl(15,d=3)

is.ok.weyl(spray(matrix(1:30,5,6)))
is.ok.weyl(spray(matrix(1:30,6,5)))
