I installed the package VariantAnnotation.I followed instructions to run the readVcf command.

I set the working directory to the folder containing the vcf file and ran the following code. I guess it is telling me that my RAM memory (8gb) is too small to open Chr1?

> library(VariantAnnotation)
> fl <- ("ALL.chr1.phase3_shapeit2_mvncall_integrated_v5.20130502.genotypes.vcf ")
> vcf <- readVcf(fl, "hg19")
Error: scanVcf: 'Realloc' could not re-allocate memory (5128192000 bytes)
  path: C:\Users\Davide\vcf1\ALL.chr1.phase3_shapeit2_mvncall_integrated_v5.20130502.genotypes.vcf
