Statistics::R::REXP::Language - an R language vector
version 1.0002
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;
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.

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.

Language
SEXPTYPE of language vectors is LANGSXP.
Perl value of the language vector is an array reference to the Perl values of its elements. (That is, it's equivalent to map {$_-to_pl}, $vec->elements>.
