Any suggestions? I have installed the latest both from CRAN mirrors

group means: split and unsplit
Took me a while but I figured out how to put in common values of
group means/counts, etc. to do the same thing as egen. lapply with
split and then unsplit.

Clustered standard errors in a panel
...to calculate weighted sums of x1 and x2... at the individual
level. I can do this at the variable level [with lapply,split and
unsplit], but would love to be able to do so over the matrix of x's.
Of course, doing by hand is less easy than an automated solution if
it exists.)

r equivalent of egen? Not tapply
...gain within
states. The value I want is the number of observations that are in
the same state as each observation.
In stata, this is simply egen statesum = count(state), by(state).
What is the r equivalent? tapply just gives me 50 observations. No
luck yet trying apply, lapply, etc.

Outreg-like command?
It would be nice to have something like stata's outreg that lets regression
output go into a form like
Specification (1) Specification (2)
Var 1 coef(1,1) coef(1,2)
se(1,1) se(1,2)
Var 2 coef(2,1) coef(2,2)
se(2,1) se(2,2)
I don't think this can be done in xtable?

Windows 2x faster than linux x86_64?
I did a speed test with a colleague. We basically have identical Lenovo
ThinkCentres. He has 8 vs my 4 G RAM, but I don't think that's the
issue.
code:
length <- 2*10^6
a <- runif(length)
b <- runif(length)
print(summary(lm(a~b)))
Running Arch x86_64 this takes about 16 to 17 seconds. I *think* I have
compiled arch=i686 and arch=x86_64 with little speed difference.

Logo Nouveau
Dear community members,
Im a graphic designer and for the last couple of months I have been working on a new logo for the Nouveau project. After sending preliminary designs to both Martin Peres and Ilia Mirkin, we have decided to share the logo in order to gather your feedback.
I would like to highlight that the logo incorporates a penguin corresponding to the linux kernel components used to
