Dear BioC users, I was wondering if a package is available which would allow to retrieve all SNPs in high LD with a given SNP (with the LD between SNPs, for example, based on Hapmap CEU samples).... similar to what is provided by the software SNAP (http://www.broadinstitute.org/mpg/snap/). I would use it to find "proxy" SNPs. Thanks in advance for any help. Regards Giuseppe
