Hi all,
I am reading in some .vcf files with the readVcf function and realized
that I cannot subset the resulting VCF objects if the info field is
empty, see example below.
Is there a workaround except for loading the info at least partially?
Thanks,
Paul
The Example:
> vcf_full = readVcf("test.vcf.gz", "hg19")
> vcf_no_info = readVcf("test.vcf.gz", "hg19", param = ScanVcfParam(
geno=c("GT","GQ"), fixed="ALT", info=NA ))
