Invisible names problem
I ran into strange behavior when removing names.
Two ways of removing names:
i <- rep(1:4, length.out=20000)
k <- c(a=1, b=2, c=3, d=4)
x1 <- unname(k[i])
x2 <- k[i]
x2 <- unname(x2)
Are they identical?
identical(x1,x2) # TRUE
but no
identical(serialize(x1,NULL),serialize(x2,NULL)) # FALSE
But problem is with serialization type 3, cause:

SEXPs and slots
Hello,
I've created this class:
setClass("example",
representation (
size = "numeric",
id = "character"
)
)
Suppose I create a new instance of this class:
> x <- new("example", 4, "id_value")
This creates an S4 object with two slots. Am I correct in thinking that
slots are "filled" by SEXPs?
