smbclient and large file support
smbclient (and smbtar) in version 2.2.7a (and prior) has problems with
large files (> 4GB). The following patch (against 2.2.7a) fixes all
known problems with this. This code has been checked into the CVS tree
in all branches as well.

Parameters setting in functions optimization
...initials parameters as indicated in the tutorials :
optim(c(40,0.5), fn=LogLiketot)
>Error in 1 - ms : 'ms' is missing
But ms is 0.5 ...
So I've tried this form :
optimx(c(30,50),ms=c(0.4,0.5), fn=LogLiketot)
with different values for the two parameters :

ANOVA non-sphericity test and corrections (eg, Greenhouse-Geisser)
I'm an experimental psychologist and when I run ANOVA analysis in
SPSS, I normally ask for a test of non-sphericity (Box's M-test). I
also ask for output of the corrections for non-sphericity, such as
Greenhouse-Geisser and Huhn-Feldt. These tests and correction factors
are commonly used in the journals for experimental and other
psychology reports. I have been switching from SPSS to R

accessing factor levels from C
Hi,
I am trying to get information about factors from a C-program. As I see,
the factors are basically integers with attribute ,,levels''. But
unfortunately I am not been able to read the levels information. I am
using:
SEXP variable, levels;
...
variable = VECTOR_ELT( data_frame, j);
switch( TYPEOF( variable)) {

set initial parameter values for GLMM estimation
Dear list members,
I look for a way (or alternative) to specify initial values when estimating
linear mixed models in R, and to avoid iterative estimation.
This is a way to control specific parameter values (eg. variance parameter
values) such that the result (F-value) is based on them. This result can
then be used for power analyses that uses the non-central F-distribution, as
is done with SAS

test for factor effect with nested glm
Dear all,
I use a nested design with lm and glm, with factor2 nested within
factor1. In order to test for the significance of both factors, I use
anova tables on the obtained models such as follows:
/> mod1<-lm(A~factor1/factor2)
> amod1<-anova(mod1, test="F")

number format in plots
Hi
It is probably simple but how to force in plot command number format:
20000, 30000, 40000 etc. instead of 2e+04, 3e+04 etc.
example of command:
plot(x=data$along, y=data$rzedna,type="l", xlim=c(0,max(data$along)),
ylim=c(200,1200), main="", xlab="length", ylab="height", cex.main=2,
cex.lab=1.5, cex.axis=1.2, lwd=2)
thanks

What does `_data` mean in transform()?
Hi All,
I meant to take the min row by row. But the result is apparently not
what I want. Changing min to pmin solve the problem.

optim seems to be finding a local minimum
Hello!
I am trying to create an R optimization routine for a task that's
currently being done using Excel (lots of tables, formulas, and
Solver).
However, otpim seems to be finding a local minimum.
Example data, functions, and comparison with the solution found in
Excel are below.
I am not experienced in optimizations so thanks a lot for your advice!

gjournal on 6.x wont build
Hi all,
I was intending on trying out gjournal on a new disk i've added in my
desktop. I had a look to see what the most recent patch provided by
Pawel and found
http://people.freebsd.org/~pjd/patches/gjournal6_20061024.patch
I created the directories as per Pawel's original post
(http://lists.freebsd.org/pipermail/freebsd-fs/2006-June/001962.html)
and the patch succeeded with no failed
