Bio::Community::Tools::Sampler - Sample organisms according to their abundance
use Bio::Community::Tools::Sampler; # get a community somehow... my $sampler = Bio::Community::Tools::Sampler->new( -community => $community ); my $member1 = $sampler->get_rand_member(); my $member2 = $sampler->get_rand_member();
Pick individuals at random (without replacement) from a community.
Note that the sampling is done based on relative abundances, and is hence affected by weights. If you need to sample based on counts instead, simply set $community->use_weights(0), before using Bio::Community::Tools::Sampler.

Function: Create a new Bio::Community::Tool::Sampler object Usage : my $sampler = Bio::Community::Tool::Sampler->new( ); Args : -community: See community(). -seed : See set_seed(). Returns : a new Bio::Community::Tools::Sampler object
Function: Get or set the community to sample from Usage : my $community = $sampler->community(); Args : a Bio::Community object Returns : a Bio::Community object
Usage : $sampler->set_seed(1234513451); Function: Get or set the seed used to pick the random members. Args : Positive integer Returns : Positive integer
Function: Get a random member from a community (sample with replacement). Usage : my $member = $sampler->get_rand_member(); Args : None Returns : A Bio::Community::Member object
Function: Create a community from random members of a community Usage : my $community = $sampler->get_rand_community(1000); Args : Number of members (strictly positive integer) Returns : A Bio::Community object
