isSymbolic: Determining whether the variant is a symbolic allele.

In PapenfussLab/StructuralVariantAnnotation: Variant annotations for structural variants

Description

Determining whether the variant is a symbolic allele.

Usage

isSymbolic(x, ...)

## S4 method for signature 'CollapsedVCF'
isSymbolic(x, ..., singleAltOnly = TRUE)

## S4 method for signature 'ExpandedVCF'
isSymbolic(x, ...)

Arguments

x	A VCF object.
...	Internal parameters.
singleAltOnly	Whether only single ALT values are accepted. Default is set to TRUE.

Details

The function takes a VCF object as input, and returns a logical value for each row, determining whether the variant is a symbolic allele.

Value

A logical list of which the length is the same with the input object.

Methods (by class)

• CollapsedVCF: Determining whether a CollapsedVCF object is a symbolic allele. Only single ALT values are accepted.

• ExpandedVCF: Determining whether a ExpandedVCF object is a symbolic allele

Examples

vcf.file <- system.file("extdata", "gridss.vcf", package = "StructuralVariantAnnotation")
vcf <- VariantAnnotation::readVcf(vcf.file, "hg19")
isSymbolic(vcf)
