[R] odd behaviour of identical

[Wacek Kusnierczyk]

given what ?identical says, i find the following odd:

x = 1:10
y = 1:10

all.equal(x,y)
[1] TRUE
identical(x,y)
[1] TRUE

y[11] = 11
y = y[1:10]

all.equal(x,y)
[1] TRUE
identical(x,y)
[1] FALSE

y
[1] 1 2 3 4 5 6 7 8 9 10
length(y)
[1] 10


looks like a bug.
