## 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)

Arguments

x	An Expression object.
object	An Abs object.
values	A list of arguments to the atom.
idx	An index into the atom.

Methods (by generic)

• to_numeric(Abs): The elementwise absolute value of the input.

• allow_complex(Abs): Does the atom handle complex numbers?

• sign_from_args(Abs): The atom is positive.

• is_atom_convex(Abs): The atom is convex.

• is_atom_concave(Abs): The atom is not concave.

• is_incr(Abs): A logical value indicating whether the atom is weakly increasing.

• is_decr(Abs): A logical value indicating whether the atom is weakly decreasing.

• is_pwl(Abs): Is x piecewise linear?

Slots

x

An Expression object.
