Dear Michael,
thank you for the enlightenment. Just for the records, here is the

This is because R keeps track of the names of an object, until there are 2
names. Thus, once it reaches 2, it can no longer decrement the named count.
In this example, 'a' reaches 2 names ('a' and 'b'), thus R does not know
that 'a' only has one name at the end.
Luke has added reference counting t
Hi,
Please consider the following code:
a <- seq.int(10) # create a
tracemem(a)
a[1:4] <- 4:1 # no internal copy
b <- a # no internal copy
b[1:4] <- 1:4 # copy, b is not a any more
a[1:4] <- 1:4 # copy, but why?
With results:
> a <- seq.int(10)
> tracemem(a)
[1] "<0x1792bc0>"
