Obtaining The Snp Rs Number With The Chromosomal Position

This question is similar to this one (Get rs number based on position).

I have a text file with SNPs in the chr:position format

 10:71086
 10:72876
 10:75794

I was wondering if there is an R package (or perhaps one in Bioconductor) that can take these as input values and provide the SNP rs number associate with them????
