An S4 class for storing VCF data.
metacharacter vector for the meta information
fixmatrix for the fixed information
gtmatrix for the genotype information
Defines a class for variant call format data. A vcfR object contains three slots. The first slot is a character vector which holds the meta data. The second slot holds an eight column matrix to hold the fixed data. The third slot is a matrix which holds the genotype data. The genotype data is optional according to the VCF definition. When it is missing the gt slot should consist of a character matrix with zero rows and columns.
See vignette('vcf_data') for more information.
