The Abs class.
This class represents the elementwise absolute value.
Abs(x) ## S4 method for signature 'Abs' to_numeric(object, values) ## S4 method for signature 'Abs' allow_complex(object) ## S4 method for signature 'Abs' sign_from_args(object) ## S4 method for signature 'Abs' is_atom_convex(object) ## S4 method for signature 'Abs' is_atom_concave(object) ## S4 method for signature 'Abs' is_incr(object, idx) ## S4 method for signature 'Abs' is_decr(object, idx) ## S4 method for signature 'Abs' is_pwl(object)
x |
An Expression object. |
object |
An Abs object. |
values |
A list of arguments to the atom. |
idx |
An index into the atom. |
to_numeric: The elementwise absolute value of the input.
allow_complex: Does the atom handle complex numbers?
sign_from_args: The atom is positive.
is_atom_convex: The atom is convex.
is_atom_concave: The atom is not concave.
is_incr: A logical value indicating whether the atom is weakly increasing.
is_decr: A logical value indicating whether the atom is weakly decreasing.
is_pwl: Is x piecewise linear?
xAn Expression object.
