ScalarObject-class: Utility classes for length one (scalar) objects

In turaganitesh/testbiocpackage1234: Test package: Base functions for Bioconductor

Description

These classes represent scalar quantities, such as a string or a number and are useful because they provide their own validity checking. The classes ScalarCharacter, ScalarLogical, ScalarInteger, and ScalarNumeric all extend their respective base vector types and can be used interchangeably (except they should always have length one).

The mkScalar factory function provides a convenient way of creating Scalar<type> objects (see the examples section below).

Usage

mkScalar(obj)

Arguments

obj	An object of type character, logical, integer, or double

Author(s)

Seth Falcon

Examples

v <- list(mkScalar("a single string"),
          mkScalar(1),
          mkScalar(1L),
          mkScalar(TRUE))
sapply(v, class)
sapply(v, length)
