genotyping or variant calling in R
Are there any good options for calling variants or even just a pileup from R? R is not ideal for this, but I'd like to integrate with other functions.
I found deepSNV::bam2R which roughly does what I ...

Filtering out 8-oxoG-derived artefacts in variant calls from cfDNA
I have cfDNA samples which were sequenced (at about 300-1000X) on a 30-gene panel via a capture-seq protocol for the purposes of calling variants on circulating tumour DNA.
However, the resulting ...
