An S4 class for an object assigning SNP positions to rs-numbers (for internal use)
An S4 class for an object assigning SNP positions to rs-numbers (for internal use)
This function gives for a vector of SNP identifiers the position of each SNP
as extracted from the Ensemble database. The database is accessed via the
R-package biomaRt.

A data.frame including the SNP positions with columns
'chromosome', 'position' and 'snp'. SNPs not found in the Ensemble database
will not be listed in the returned snp_info object, SNPs with multiple
positions will appear several times.
