showMapNames

Mega2R allows several different physical and genetic maps to be stored and used to select
 positions. This function shows the association between map number and map name.

Uses as input genetic data that have been reformatted and
stored in a 'SQLite' database; this database is initially created
by the standalone 'mega2' C++ program (available freely from
<https://watson.hgen.pitt.edu/register/>). Loads and manipulates
data frames containing genotype, phenotype, and family
information from the input 'SQLite' database, and decompresses
needed subsets of the genotype data, on the fly, in a memory
efficient manner. We have also created several more functions
that illustrate how to use the data frames as well as perform
useful tasks: these permit one to run the 'pedgene' package to
carry out gene-based association tests on family data using
selected marker subsets, to run the 'SKAT' package to carry out
gene-based association tests using selected marker subsets, to
run the 'famSKATRC' package to carry out gene-based association
tests on families (optionally) and with rare or common variants
using selected marker subsets, to output the 'Mega2R' data as a
VCF file and related files (for phenotype and family data), and
to convert the data frames into CoreArray Genomic Data Structure
(GDS) format.
