Thanks, Hadley for bringing this up:-)
I am teaching R and I can suggest 5 different definitions of 'vector':
a) vector as a collection of homogeneous objects, indexed by [ ] (more
precisely atomic vector). Sometimes you hear that in R, "everything is a
vector", but this is only true for atomic

Apparently your username/password are wrong. Can you clone/push from other
repos?
You do not need authorization when cloning a public repo, so even incorrect
credentials may work (haven't tested this though). But for push you have
to have that in order.
I suggest you create ssh keys, upload tho

Can anyone explain me the following behavior:

'rowsum()' seems to add row names to the resulting matrix, corresponding to
the respective 'group' values. This is very handy, but it is not
documented. Should the documentation mention it so it could be relied upon
as part of API?

I am referring to base::rowsum(), not rowSums(). For some reason I cannot
access it's help on my computer but the online documentation (R-devel
version) states:

I have done this using attributes:
fr <- function(x) { ## Rosenbrock Banana function
x1 <- x[1]
x2 <- x[2]
ans <- 100 * (x2 - x1 * x1)^2 + (1 - x1)^2
attr(ans, "extra1") <- 1:10
attr(ans, "extra2") <- letters

}
Not sure if this works in your case though.
