Bio::Community::Meta::Gamma - Calculate the gamma diversity of a metacommunity
use Bio::Community::Meta::Gamma; my $gamma = Bio::Community::Meta::Gamma->new( -community => $community, -type => 'richness' ); my $richness = $gamma->get_gamma;
The Bio::Community::Meta::Gamma module calculates the gamma diversity of a group of communities (provided as a metacommunity object). Higer gamma diversity values indicate more diverse metacommunities.
This module supports the same diversity metrics provided in Bio::Community::Alpha. In addition, you can use:
Bias-corrected chao2 estimator, which is based on the number of members present in exactly 1 and 2 samples.
First-order jackknife estimator for incidence data.
Second-order jackknife estimator for incidence data.
Incidence-based Coverage Estimator (ICE).

User feedback is an integral part of the evolution of this and other Bioperl modules. Please direct usage questions or support issues to the mailing list, email@example.com, rather than to the module maintainer directly. Many experienced and reponsive experts will be able look at the problem and quickly address it. Please include a thorough description of the problem with code and data examples if at all possible.
If you have found a bug, please report it on the BioPerl bug tracking system to help us keep track the bugs and their resolution: https://redmine.open-bio.org/projects/bioperl/

The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _
Function: Create a new Bio::Community::Meta::Gamma object Usage : my $gamma = Bio::Community::Meta::Gamma->new( ... ); Args : -metacommunity : See metacommunity(). -type : See type(). Returns : a new Bio::Community::Meta::Gamma object
Function: Get or set the communities to process, given as a metacommunity. Usage : my $meta = $gamma->metacommunity; Args : A Bio::Community::Meta object Returns : A Bio::Community::Meta object
Function: Get or set the type of gamma diversity metric to measure. Usage : my $type = $gamma->type; Args : String for the desired type of gamma diversity ('observed' by default). See L</METRICS> for details. Returns : String for the desired type of gamma diversity
