Arith {disordR}

Arithmetic operations

Description

Arithmetic operations including low-level helper functions

Usage

disord_inverse(a)
disord_mod_disord(a,b)
disord_mod_numeric(a,b)
disord_negative(a)
disord_plus_disord(a,b)
disord_plus_numeric(a,b)
disord_power_disord(a,b)
disord_power_numeric(a,b)
numeric_power_disord(a,b)
disord_prod_disord(a,b)
disord_prod_numeric(a,b)
disord_arith_unary(e1,e2)
disord_arith_disord(e1,e2)
disord_arith_numeric(e1,e2)
numeric_arith_disord(e1,e2)

Arguments

a, b

at least one is a disord object

e1, e2

Formal arguments for S4 dispatch

Details

Basic low-level arithmetic operations, intended to be called from S4 dispatch.

These functions return a disord object or a regular vector as appropriate. Consistency is required. The hash is set to be that of the disord object if appropriate.

Value

Return a disord object or logical
