Error in validObject(.Object) when reading 'representations.vcf' file

[sanghoonleeeins]

Hi,

I installed "StructuralVariantAnnotation" package and tried to read "representations.vcf" but I got an error message below. I am using R 4.5.0, so I think it should work. Could help me solve this issue?

library(StructuralVariantAnnotation)
vcf <- VariantAnnotation::readVcf(system.file("extdata", "representations.vcf", package = "StructuralVariantAnnotation"))

Error in validObject(.Object) :
invalid class “CollapsedVCF” object: superclass "ExpData" not defined in the environment of the object's class
