frab (version 0.0-6)

namedvector: Named vectors and the frab package

Description

Named vectors are closely related to frab objects, but are not the same. However, there is a natural coercion from one to the other.

Usage

as.namedvector(v)
is.namedvector(v)
is.namedlogical(v)
is.unnamedlogical(v)
is.unnamedvector(v)

Value

Function is.namedvector() returns a boolean, function as.namedvector() returns a named vector.

Arguments

v

Argument to be tested or coerced

Details

Coercion and testing for named vectors. Function nv_to_frab(), documented at frab.Rd, coerces a named vector to a frab.

Examples

x <- c(a=5, b=3, c=-2,b=-3, x=33)
is.namedvector(x)
as.namedvector(frab(x))

x <- c(a=5, b=3, c=-2)
y <- c(p=1, c=2, d= 6)

x
y
x+y

frab(x) + frab(y)
