wrapr (version 1.9.6)

ApplyTo: Apply a single argument function to its argument.

Description

If x is a UnaryFn instance this function returns a new UnaryFnList representing the composite function c(f, x) which is interpreted as the function x(f(.)) (composition from left to right). Otherwise evaluate f(x) (application from left to right).

Usage

ApplyTo(f, x, env = parent.frame())
# S4 method for UnaryFnList,UnaryFnList
ApplyTo(f, x, env = parent.frame())
# S4 method for UnaryFnList,UnaryFn
ApplyTo(f, x, env = parent.frame())
# S4 method for UnaryFn,UnaryFnList
ApplyTo(f, x, env = parent.frame())
# S4 method for UnaryFn,UnaryFn
ApplyTo(f, x, env = parent.frame())
# S4 method for UnaryFnList,ANY
ApplyTo(f, x, env = parent.frame())
# S4 method for PartialNamedFn,ANY
ApplyTo(f, x, env = parent.frame())
# S4 method for PartialNamedFn,UnaryFnList
ApplyTo(f, x, env = parent.frame())
# S4 method for PartialNamedFn,UnaryFn
ApplyTo(f, x, env = parent.frame())
# S4 method for PartialFunction,ANY
ApplyTo(f, x, env = parent.frame())
# S4 method for PartialFunction,UnaryFnList
ApplyTo(f, x, env = parent.frame())
# S4 method for PartialFunction,UnaryFn
ApplyTo(f, x, env = parent.frame())
# S4 method for SrcFunction,ANY
ApplyTo(f, x, env = parent.frame())
# S4 method for SrcFunction,UnaryFnList
ApplyTo(f, x, env = parent.frame())
# S4 method for SrcFunction,UnaryFn
ApplyTo(f, x, env = parent.frame())

Arguments

f

object of S4 class derived from UnaryFn.

x

argument.

env

environment to work in.

Value

f(x) if x is not a UnaryFn else f composed with x.
