[BioC] problem about using 'rtracklayer' to retrieve chromosome position of SNPs

using rtracklayer, it's possible to retrieve data with functions of
'ucscTableQuery' and 'getTable'.
however, these functions could only retrieve data given a genomic range.
For example, using following code could retrieve snps between 10000 to 20000
basepair on chromosome 2.
ucscTableQuery(session, "snp129",GenomicRanges(10000,20000, 2))->todo
my question is how to retrieve data using identifiers(names/accessions).
for example, is it possible to retrieve chromosome position given the rs number
of several SNPs, such as
is there any function in 'rtracklayer' package can do this?
