Hi Vincenzo Apologies for the very delayed response! There is a function named vcf2sm in package GGtools that might help. I don't have any direct experience with this but thought I'd flag it up.

Thanks for mentioning this Richard. The GGtools vcf2sm has a limited use case at present -- translating calls published by the 1000 genomes project to snpStats SnpMatrix instances. Only the genotype call values are used; information on call uncertainty is not yet propagated by vcf2sm. The samtools suite includes bcftools. As I understand it, samtools mpileup will generate vcf or bcf and such files can be imported or scanned using Rsamtools scanBcf. Last time I checked, bcftools did not work with 1000 genomes-generated VCF.
