Provides a collection of utilities that allow programming with R's operators. Routines allow classifying operators, translating to and from an operator and its underlying function, and inverting some operators (e.g. comparison operators), etc. All methods can be extended to custom infix operators.
This package provides an extensible collection of utilities for programming with operators that appear in language objects such as formulas, calls and expressions. Various routines allow operations classifying operators, translating between an operator and its underlying function, and inverting some types of operators, etc. All methods can be extended to custom infix operators.
operators: Get list of known operators
setOperator: Register a new type of operator
removeOperator: UNregister an operator
is.operator: Test if object is an operator
can.operator: Can object be coerced to an operator
as.operator: Coerce object to an operator if possible
operator.type: get the type of an operator
