Creating users "on - the - fly"
I guess I didn't want to litter the users table either - it just seems
"wrong" to be actually adding things to the host when it is really so
transient. It feels like it should be LDAP-ish. Just ask the server
for the keys and do a one-off authentication. But I've seen even LDAP
creates the user directories.
I see that 2.6 kernels can have some 4B users, which should last me a

Constrained least squares
Is there a function in R for constrained linear least squares?
I used the matlab function LSQLIN: my aim is to obtain
non-negative regression coefficients which sum 1.
Thanks in advance,

No, i'm suggesting that when you want to look up the user, use NSS to
find the username and map it to a numeric user ID and the other
information that is typically found in

Need help in calculating studentized residuals/leverage values of non-linear model [nls()]
Hi there,
I hope I can get advice regarding the calculation of leverage values or
studentized residual values of a non-linear regression model. It seems like
rstudent() does not work on a nls object.
Many thanks in advance!

lpSolve and mixed signs
Hi R People:
If you have a linear programming problem in which
some of the constraints have the "<=", some
have ">=" and some have "=", all in the same problem,
should the solver work?
I'm having trouble with that. Any help much appreciated!
Sincerely,

How to label specific points on a scatterplot
Command I am using for the plot:
plot(Raw[][Plate==101]~well[][Plate==101], xlab="Well", ylab="Raw",
main="Plate 101")
I only want to label points on the graph where well equals B13, G13, K14 and
N14 with the name of the well.
Thank you for your help.

Creating users "on - the - fly"
Hi all.
I have a situation that I wonder someone may have run into - or has a
direction I should dig / develop in.
Let's say I have a system with 1M "users". Their public keys are
stored in a database, and I can access them via a web call.
I have a few servers which should allow those users access.
Some constraints to make it non-crazy.
The users can only reverse tunnel. They

Removing Outliers Function
I am working on a function that will remove outliers for regression analysis.
I am stating that a data point is an outlier if its studentized residual is
above or below 3 and -3, respectively. The code below is what i have thus

x = c(1:20)
y = c(1,3,4,2,5,6,18,8,10,8,11,13,14,14,15,85,17,19,19,20)

Re: Creating users "on - the - fly"
This is a good suggestion - and maybe I'm not totally clear on the
restrictions...
So - in these situations gitolite will actually append things to your
authorized_keys file. Which can get very long. And after a while - it
gets *very* long. I think I saw comments that it should be limited to
about 20k or so. And around 20k the look up times are in the seconds.
So that wouldn't be enough

multi-level modeling & R?
A colleague was asking me if R does multi-level
modelling as opposed to multiple regression. Since I
have no knowledge of multi-level modelling (except 5
minutes googling ) I thought that I would as here.
Does are offer any multi-level modeling packages? It
looked like arm might be one but I was not sure.

studentized and standarized residuals
Hi,
I must be doing something silly here, because I can't get the studentised
and standardised residuals from r output of a linear model to agree with
what I think they should be from equation form.
Thanks in advance,
