Hi Michael, I found the following bug when coercing a list to a SimpleList with IRanges devel (not with IRanges release):
library(IRanges) x <- list(a=matrix(rep("a", 6), nrow=3), b=array(rep("b", 24), dim=c(3,4,2))) Then: > sapply(as(x, "SimpleList"), class) a b "matrix" "matrix" > lapply(as(x, "SimpleList"), dim) $a [1] 3 2 $b [1] 24 1 The array was turned into a matrix! Note that the SimpleList() constructor behaves as expected: > sapply(SimpleList(x), class) a b "matrix" "array" > lapply(SimpleList(x), dim) $a [1] 3 2 $b [1] 3 4 2 Do you think you can have a look?
