Description

This S4 function convert or creates a Map object. The input can be either a data frame or a list of Chrom objects. If the data for minor allele frequency (Maf) are missing in the input, their values are to be NAs. The default values for "Type" and "Status" are "C" and 0, repectivelyl, if they are missing in the input.
