Dear all,
When I use makeVRangesFromGRanges (R package VariantAnnotation), I got the following error,
Error in as(mcols(gr)[, i], type[i]) : no method or default for coercing "factor" to "NA"
My operations shown below
> library(SomaticSignatures)
> data(ov_tcga, package = "SomaticCancerAlterations")
> ov_tcga_2_vr <- makeVRangesFromGRanges(ov_tcga, ref.field="Reference_Allele", alt.field = "Tumor_Seq_Allele2")
Error in as(mcols(gr)[, i], type[i]) :
no method or default for coercing "factor" to "NA"
Can anybody help me to solve this problem? Thank.
