models for square tables
I've posted a sample file for estimating loglinear models for square
tables (mobility models) at http://www.xs4all.nl/~jhckx/mcl/R/
Comments and suggestions are welcome.

R search engine and Mozilla
...which works fine. However, I rather like
Mozilla. Any suggestions on what the problem is here? Is this an R
problem or should I report it to Mozilla.org? I'm afraid I'm
unfamiliar with JavaScript or I might have a bit of a clue as to
what's going on.
Advanced thanks for any help,

mcl models, percentages
..., the mean absolute
difference is 0.00069. Stata's "clogit" and "mlogit" produce the same
estimates and match those of "multilog" to at least 6 decimal points
accuracy. See the notes in http://www.xs4all.nl/~jhckx/R/mcl.html Can
anyone shed any light on this?

bug in CrossTable (package:gregmisc) (PR#2480)
Full_Name: John Hendrickx
Version: 1.6.0
OS: Windows 98
Submission from: (NULL) (137.224.174.216)
CrossTable in the "gregmisc" package fails when the fisher.exact test produces
an error (I suspect this is because the number of cases is too large). This can
be fixed using "FTt <- try(fisher.test(t, altern...

modifying ftable to allow percentages (wishlist) (PR#2606)

Version: 1.6.2
OS: Windows XP
Submission from: (NULL) (80.126.78.108)
(This is not a bug report but a request to add a feature to future versions of
R. Hope this is an appropriate place).
I'd like to suggest adding an option to ftable to allow percentages. It would be
easy to do and backward...

comments on documentation
...disagree with the import/export documentation, that importing
files from foreign packages should be avoided (chapter 3). This will
often be the starting point for new users who have most of their data
in a foreign format and will usually be the quickest and most
practical method in any case.

(multiway) percentage tables
...ssed on to
ftables for formatting multiway tables.
I'd like to see something like ctab in R-base at some point in the
future. Perhaps it could be integrated in ftable? Perhaps I'll try
that myself as a next project. I'm still learning R so comments on
ctab are most welcome.
Best,

perturb package for evaluating collinearity
...dent variables.
Version 1 of perturb was available from my website. This new version
makes it much easier to reclassify categorical variables. In
addition, colldiag now has a "fuzz" option to suppress printing of
small variance decomposition values.

New version of "catspec" package
...able.
The second special (set of) models is "sqtab", for estimating
loglinear models for square tables (aka "mobility models") such as
symmetry, quasi-independence. One application can be to specify such
models as multinomial logistic models with covariates, using mclgen.

Dear list,
I am trying to create a three-way table with percent occurrence

how to compute condition index?
is there any existing function for computing condition index?
" analysing multivariate data" say that we can use condition index to check
multicollinearity.saying that we can get it via SVD. The elements of the
diagnoal matrix are the standard deviations of the uncorrelated vectors. the
condition index is the ratio of the largest of these numbers to the smallest.
so if i have a data

different login_greeting for pop3 & imap?
Hi,
I have a tiny feature request for Dovecot: could it optionally have
different login_greetings for pop3 and imap connections? e.g. I want
it to say "Dovecot on pop.mycompany.com ready" on pop3 connections and
"Dovecot on imap.mycompany.com ready" on imap connections. Would that
be possible?
TIA,

LDAP: bind to LDAP server instead of retreiving a password from it?
Hi,
Dovecot currently treats an LDAP user/password database the same way as a text
or SQL based database: it just tries to retreive the (hashed) password for a
given username. LDAP however has the capability to authenticate the user
itself: dovecot could try to bind to LDAP with the given username and password,
and if authentication succeeded, the LDAP server returns the other info (uid,

Are host names a secret?
Some time ago I added the ability for IMAP clients to fetch messages'
GUIDs using FETCH X-GUID command. Because of a bug it wasn't working in
1.2.0 or 1.2.1, but I've fixed it now. But now I'm starting to wonder:
With Maildirs the GUIDs are the maildir base filenames, which contain
host names. Is it a bad idea to expose them to users?

maildir/cur/ - file names
Hi All.
I want to know how filenames are changed by dovecot e,g more details on how it renames the files when a mail is read.
For read mails i found that it appends an S.
