Create a matrix with presence and absence

## NAME

Bio::Roary::PresenceAbsenceMatrix - Create a matrix with presence and absence

## VERSION

version 3.13.0

## SYNOPSIS

Create a matrix with presence and absence. Since its computationally intensive to generate the inputs, calculate them once in the GroupStatistics module and pass them through.\
    use Bio::Roary::PresenceAbsenceMatrix;

```
   my $obj = Bio::Roary::PresenceAbsenceMatrix->new(
     annotate_groups_obj => $annotate_groups_obj,
     output_filename     => 'gene_presence_absence.Rtab',
     sorted_file_names   => $sorted_file_names,
     groups_to_files     => $groups_to_files,
     num_files_in_groups => $num_files_in_groups,
     sample_headers      => $sample_headers,
   );
   $obj->create_matrix_file;
```
