permissions of newly created mailboxes only with dovecot-lda and posix acls
Hi!
I am experiencing troubles concerning the inheritance of the setgid bit if a new mailbox is created with dovecot-lda.
If it is created with dovecot/imap, everything works fine.
dovecot-lda is called from postfix like this:

Problem in loading all packages all at once
Hi All
Please see the Rprofile file which i have modified as follows and after
that when I start R then I see that R says to me "TRUE" for all the
packages implying that all loaded at once.
But when i try to use commands as simple as help("lm"), it doesnt work nor
any of the menu "Packages" is not working.
Although the regression using lm ( Y ~ X ) is working

How to embed residual dot plots of BHH2::anovaPlot(...) into plotMeans(...)?
Dear R fans,
I am preparing a lecture discussing the paper of Wilkinson and APA
Task Force on Statistical Inference (1999, American Psychologist, 54,
594-604.) I'd like to demo their Figure 3B (p. 602) with R. That is to
add plotMeans(...) with dots of BHH2::dotPlot(...) . Is there any
elegant script to do the job?
Thanks

help on permutation/randomization test
Hi,
I have two groups of data of different size:
group A: x1, x2, ...., x_n;
group B: y1, y2, ...., y_m; (m is not equal to n)
The two groups are independent but observations within each group are
not independent,
i.e., x1, x2, ..., x_n are not independent; but x's are independent from y's
I wonder if randomization test is still applicable to this case. Does

Randomisation tests
Hi,
I want to ue a randomisation test, to compare two sample means, for a
small set of data, I've looked at towt.permutation, perm.test and
permtest, as well as permTS(), which is the best one to use for such a
simple purpose? I know perm.test package isn't used anymore and coins
recommended, but reading the manual I couldnt find the function most

MANOVA permutation testing
Hi,
I've got a dataset with 7 variables for 8 different species. I'd like
to test the null hypothesis of no difference among species for these
variables. MANOVA seems like the appropriate test, but since I'm
unsure of how well the data fit the assumptions of equal
variance/covariance and multivariate normality, I want to use a
permutation test.
I've been through CRAN looking at

Can anyone suggest some r packages for Experimental Designs, specifically for choice and conjoint??? (or is intersted in helping me make 1)
Afternoon everyone,
I''ve spent the last week or so looking at all the experimental design
packages I can find in R. AlgDesign, design.conf and BHH2 being the best one
I could find.
Unfortunately none of these do a particularly good job for complex designs,
in particular for conjoint or discrete choice. (or perhaps they do, and I
can''t make them work correctly)

combn(n, k, ...) and all its re-inventions
It seems people are reinventing the wheel here:
The goal is to generate all combinations of 1:n of size k.
This (typically) results in a matrix of size k * choose(n,k)
i.e. needs O(n ^ k) space, hence is only applicable to
relatively small k.
Then alternatives have been devised to generate the combinations
"one by one", and I think I remember there has been a

(OT) Does pearson correlation assume bivariate normality of the data?
Dear all,
The other day I was reading this post [1] that slightly surprised me:
"To reject the null of no correlation, an hypothsis test based on the
normal distribution. If normality is not the base assumption your

dont mean much (the value of the coefficient is not reliable) " (BOB

restricted permutations in permtest()?
Hallo List,
I'm trying to implemement a restricted permutation scheme in permutest(). More
precisely I have dependence in my data that should be allowed for in the
permutation - I simulated the problem in the example of the vegan documentation
p.24:

Buglet in qbeta?
Hi,
I sometimes play around with extreme parameters for distributions and
found that qbeta is not always monotone as the following example shows.
I don't know whether this is serious enough to submit a bug report (as
this example is near to the limitations of floating point arithmetic).
