Confidence interval on parameters from optim function
Hi everyone,
I have two questions:
I would like to get confidence intervals on the coefficients derived
from the optim() function.
I apply optim() to a given function f
> res <-
optim(c(0.08,0.04,1.),f,NULL,method="L-BFGS-B",lower=c(0.,0.,0.))
And I would like to get the p-value and confidence intervals associated
with

My second question deals with error message. I

Use of .First() in Mac OS X gui
Hi,
I am having problems using .First() with the Mac OS X gui version of R 2.7.2
(under OS X 10.5.5); .First is ignored on startup. .First() does work in the
command-line version of R under Mac OS X but my specific task requires the
gui version. I can find no reference to this issue in the Mac OS X FAQ or in
other manuals, does anyone have a solution for this?
Thanks,
Ian

R and McAfee 8.5
Hi,
I have been working with R for the last year and using the UKFSST package to look at satellite tag track data and SST information. Fpr those not familiar, the package uses the positions estimated by the satellite tags themselves and the associated SST data from servers (in this case, from the University of Hawaii and the NOAA Coastwatch website) for the time preiod to estimate a reasonable

Passing a list object to lapply
Hello,
I'm having difficulty passing an object name to a lapply function. Can
somebody tell me the trick to make this work?

R seems to "stall" after several hours on a long series o f analyses... where to start?
You can test if the problem is accumulation in memory registers, which is
certainly what this sounds like. Just do a loop over a reasonably small
number of iterations and store or print the time between each iteration. If
memory accumulation it will run optimally for the first few iterations,
after which the time will increase noticeably (essentially exponentially,
hence ultimately freezes up). If

Plot contour over filled contour
Dear R-users,
I haven't found a way in the searchable archive to overplot a contour
(lines) over a surface.
I have a (n,m) matrix that represents sea surface temperature that I
have plotted using image.plot(), filled.contour() or image(). I would
like to overplot this image with some contour lines of mixed layer depth
values(same size matrix). How can I do this?
Any help is appreciated,

glmmPQL & Wald-type F-tests
Hello,
Might anyone know how to conduct Wald-type F-tests of the fixed
effects estimated by glmmPQL? I see this implemented in SAS (GLIMMIX),
and have seen it recommended in user group discussions, but haven't come
across any code to accomplish it. I understand the anova function treats
a glmmPQL fit as an lme fit, with the test assumptions based on maximum
likelihood, which is inappropriate

HDF5 and R 2.8.0patched
Hi Everyone,
I have updated my R version from 2.7 to 2.8 (patch) and since then I can
not open HDF5 files that I saved previously with the command hdf5save
from the hdf5 library.
As anyone had that problem yet?
Any help would be appreciated. Thanks

Attached file following download failure
Hello,
I'm working with a package that uses download.file in functions to
extract information from remote databases. My current environment is
Windows XP Pro SP3, R 2.7. A full extraction can be a great deal of
data, so the download is accomplished in generally manageable packets,
such that a single download will result in many files, which are written
to a directory. It is not uncommon for a

password synchronization - smbpasswd for ordinary users
I have Samba 2.2.3a running on Tru64 Unix v4.0f (?)
I have Win NT4.0 (sp6a) as our local PC OS.
I have created a Samba password file for users.
I've tried several permutations, but currently I have
security = user
encrypt passwords = yes
unix password sync = yes
username map = /../../../usermap.txt
I also have standard password encryption on the NT side, i.e. not plaintext.

calcMin
I tried to use calcMin with a function that uses a number of ...
arguments (all args from resid on) besides the vector of parameters
being fit. Same idea as optim, nlm, nlminb for which this form of ...
syntax works. But with calcMin I get an error regarding unused
arguments. No partial matches to previous arguments that I can see.
Anybody know the reason or fix for this?

constrained optimisation in R.
i want to estimate parameters with maximum likelihood method with contraints (contant numbers).
for example
sum(Ai)=0 and sum(Bi)=0
i have done it without the constraints but i realised that i have to use the contraints.
Without constraints(just a part-not complete):
skellamreg_LL=function(parameters,z,design)
{
n=length(z);
mu=parameters[1];
H=parameters[2];
Apar=parameters[3:10];

How to give more rights to users ?
Hello Everybody,
I've just finished to install a SAMBA domain with LDAP authentication.
All works fine :). The clients runs Windows 2000 Pro or Windows XP. The
problem is that a simple user can't install or modify some system
parameters and in my office it's needed by some users. So I would like
to know how to give these rights to users logged in the domain on their
local system
