I am trying to use function c() to combine two Views, but get an error.

> library(XVector)
> v= Views(1:10,1,2)
> c(v, v)
Error in unclass(target) : cannot unclass an external pointer

> dna = DNAString("ACTGCA")
> v = Views(dna, IRanges(1, 2:5))
> c(v,v)
Error in unclass(target) : cannot unclass an external pointer
