[Rd] Unexpected behavior with inheritance and using S3 classes as slots in S4 class

Hi all, I have a situation where I'm trying to use S3 classes as slots in an S4 class and am running into some problems with inheritance. My example: ## with S3 classes a <- function(x) structure(x, class = "a") b <- function(x) structure(x, class = c("b", "a")) setOldClass(c("a", "b")) a_1 <-
