Drop redundant information

Coerce scalar Clifford objects to numeric

Usage

drop(x)
drop_clifford(x)

Arguments

x

Clifford object

Details

If its argument is a pure scalar clifford object, or the pseudoscalar, coerce to numeric. Scalar or pseudoscalar clifford objects are coerced to an unnamed numeric vector (of length 1). Checking for being the pseudoscalar requires that option maxdim be set.

Function drop() is generic, dispatching to helper function drop_clifford() for clifford objects. The logic of drop_clifford() prevents is.pseudoscalar() being called if maxdim is NULL.

Note

Many functions in the package take drop as an argument which, if TRUE, means that the function returns a dropped value.

Examples

drop(as.clifford(5))
#> [1] 5

const(rcliff())
#> [1] 6
const(rcliff(),drop=FALSE)
#> Element of a Clifford algebra, equal to
#> scalar ( 7 )
