Accessing maildir snapshots through dovecot / namespace
Hi,
I've the following setup :
- FreeBSD 9.0 / Dovecot 2.1.7
- Maildir storage over iSCSI (Dell MD3200i)
- Virtual users over LDAP
to render the storage snapshots available through
dovecot (to allow my users to browse their mail history).
Here is my conf :

type = private
inbox = yes

owner and group permission
Sirs,
We've just successfully upgraded our samba server from 2.0 to 3.0.
Access from windows clients and linux clients particularly RH7.3 and
RH9.0 has no problem accessing the files and saving them.
Unfortunately, we also have Mandrake and Knoppix workstations and in
which we're having problems on the mounting of the samba shares.
Mandrake and Knoppix basically uses the original

Recipe for "admin-less restore"
Is there a way for setting up dovecot in such a way that a user can
"jump back in time" to an old mailbox "state" in order to retrieve his
accidentially deleted mail?

table elemets testing
Hi everybody,
i'm dealing with some percentage tables, of which i should test rowwise if
the entries are sgnificantly equal or not. Namely, on row 1, test H0:
element 1= element2, H0: element 1= element3...H0: element 2= element3...H0:
element n-1= element n. The same on the other rows.
Anybody knows how this can be done in quick way? I don't have large
matrices, but it seems quite

Newbie q. need some help understanding this code.
dear all.
Would someone be kind and willing to explain the code
below for a person who has never used R? ( that is if
one has enough time and inclination)
It implements gillepsie's stochastic algorithm for
Lotka Volterra model.
What would help me tremendously is to see the
breakdown of the line by line code into plain english.
thanks for any insights or other comments.

{10,20,30}>={25,30,15}
Hi There,
Using t.test to test hypothesis about which one is greater, A or B?
where A={10,20,30},B={25,30,15}.
My question is which of the following conclusions is right?
#################hypothesis testing 1
h0: A greater than or equal to B
h1: A less than B
below is splus code
A=c(10,20,30)
B=c(25,30,15)
t.test(c(10,20,30),c(25,30,15),alternative="less")
output:

about different bandwidths in one graph
Thank you in advance.
Now I want to make comparison of the different bandwidth h in a normal
distribution graph.
This is the table of bandwidth h: thumb rule (normal)--0.00205; thumb
rule(Epanech.)--0.00452; Plug-in (normal)--0.0009;
Plug-in(Epanech.)--0.002.
this is the condition: N=1010 data sample is from normal distribution
N(0,0.0077^2). The grid points are taken to be [-0.05,0.05] and

Skewness test
Hi,
is there a test for the H0 skewness=0 (or with skewness as test
statistic and normality as H0) implemented in R?
Thank you,

Automatically extract info from Granger causality output
Dear Community,
this is my first programming in R and I am stuck with a problem. I
have the following code which automatically calculates Granger
causalities from a variable, say e.g. "bs" as below, to all other
variables in the data frame:
log.returns<-as.data.frame( lapply(daten, function(x) diff(log(ts(x)))))
y1<-log.returns$bs
y2<- log.returns[,!(names(log.returns) %in%

Joint test
Dear All,
I am estimating a Cox proportional hazard model, with several interactions
of the type a*z + a*y + a*x + b*z + b*y + b*x.
I need to know if the first three (the "a"s) are jointly significantly
different from the last three (the "b"s). I have tried several approaches,
but have been unsuccessful.
Here's the model, and the code I came up with, with the obvious

permutation test for linear models with continuous covariates
Hi I was wondering if there is a permutation test available in R for linear
models with continuous dependent covariates. I want to do a test like the
one shown here.
bmi<-rnorm(100,25)
x<-c(rep(0,75),rep(1,25))
y<-rnorm(100)+bmi^(1/2)+rnorm(100,2)*x+bmi*x
H0<-lm(y~1+x+bmi)
H1<-lm(y~1+x+bmi+x*bmi)

Selecting Best Model in an anova.
Hello,
I have a simple theorical question about regresion...
Let's suppose I have this:
Model 1:
Y = B0 + B1*X1 + B2*X2 + B3*X3
and
Model 2:
Y = B0 + B2*X2 + B3*X3
I.E.
Model1 = lm(Y~X1+X2+X3)
Model2 = lm(Y~X2+X3)
The Ajusted R-Square for Model1 is 0.9 and the Ajusted R-Square for Model2 is 0.99, among many other significant improvements.
And I want to do the anova test to choose the best

Help writing a Scheffe Contrast function for R
Hello,
As a new user of R (less than a month) I have got my hands on several books and am pouting through the net looking for help in gaining understanding of this powerful tool. I am becoming more proficient with using basic functions to conduct basic statistics. I am now looking to learn how to write code. After a few small worthless functions I decided to try to create a function that was

shapiro wilk normality test
Hi everybody,
somehow i dont get the shapiro wilk test for normality. i just can?t
find what the H0 is .
i tried :
shapiro.test(rnorm(5000))
Shapiro-Wilk normality test
data: rnorm(5000)
W = 0.9997, p-value = 0.6205
If normality is the H0, the test says it?s probably not normal, doesn
?t it ?
5000 is the biggest n allowed by the test...
are there any other test ? ( i know qqnorm

How to compute p-Values
Hello.
How can I compute the Bootstrap p-Value for a one- and two sided test, when I have a bootstrap sample of a statistic of 1000 for example?
My hypothesis are for example:
1. Two-Sided: H0: mean=0 vs. H1: mean!=0
2. One Sided: H0: mean>=0 vs. H1: mean<0

Null and Alternate hypothesis for Significance test
Hi,
I had a question about specifying the Null hypothesis in a significance
test.
Advance apologies if this has already been asked previously or is a naive
question.
I have two samples A and B, and I want to test whether A and B come from
the same distribution. The default Null hypothesis would be H0: A=B
But since I am trying to prove that A and B indeed come from the same
distribution, I think
