Hello Martin,
Below is a reduced version of our code that doesn't produce an error in
r61643 but does in 2.15.2.
Thanks,
-- François
setClass("phylo4",
representation(edge="matrix",
annote="list"),
prototype = list(edge = matrix(nrow = 0, ncol = 2),
annote = list())
)
setGeneric("phylo4", function(x, ...) { standardGeneric("phylo4")} )
setMethod("phylo4", "matrix",
function(x, annote = list()) {
res <- new("phylo4")
res@edge <- x
res@annote <- annote
res
}
)
edge <- structure(c(6L, 7L, 8L, 8L, 9L, 9L, 7L, 6L, 7L, 8L, 1L, 9L,
2L, 3L, 4L, 5L), .Dim = c(8, 2))
phylo4(edge, annote="foo")
