lambdass: Syntax sugar of making an anonymous function

In TobCap/lambdass: lambda syntax-sugar

Description

Syntax sugar of making an anonymous function

Usage

as.formals(x, value = list(quote(expr = )))

is.formals(y)

f.r(..., env_ = parent.frame())

f.(...)

Arguments

x	coerced to character (internally STRSXP).
value	a default value for making formal parameters.
y	expected to be a pairlist object which is all different named.
...	If one argument is passed, that is parsed as lambda's body. If two or more argument is passed, the last part is parsed as lambda's body and the rest are parsed as formal parameters for lambda.
env_	an environment in which call object is evaluated.

Examples

 f.(x, x + 1) # => function(x) x + 1
 f.(x, f.(y, x + y)) # => semantics is: function(x) function(y) x + y
 Reduce(f.(x, y, x + y), 1:10) # => 55
 Filter(f.(x, x %% 2 == 0), 1:10) # => c(2L, 4L, 6L, 8L, 10L)
