NAME

Statistics::R::REXP::Language - an R language vector

VERSION

This documentation refers to version 0.03 of the module.

SYNOPSIS

use Statistics::R::REXP::Language

# Representation of the R call C<mean(c(1, 2, 3))>:
my $vec = Statistics::R::REXP::Language->new([
    Statistics::R::REXP::Symbol->new('mean'),
    Statistics::R::REXP::Double->new([1, 2, 3])
]);
print $vec->elements;

DESCRIPTION

An object of this class represents an R language vector (LANGSXP). These objects represent calls (such as model formulae), with first element a reference to the function being called, and the remainder the actual arguments of the call. Names of arguments, if given, are recorded in the 'names' attribute (itself as Statistics::R::REXP::Character vector), with unnamed arguments having name ''. If no arguments were named, the language objects will not have a defined 'names' attribute.

METHODS

Statistics::R::REXP:Language inherits from Statistics::R::REXP::Vector, with the added restriction that its first element has to be a Statistics::R::REXP::Symbol or another Language instance. Trying to create a Language instance that doesn't follow this restriction will raise an exception.

BUGS AND LIMITATIONS

Classes in the REXP hierarchy are intended to be immutable. Please do not try to change their value or attributes.

There are no known bugs in this module. Please see Statistics::R::IO for bug reporting.
