gamm in mgcv random effect significance
Dear R-helpers,
I'd like to understand how to test the statistical significance of a
random effect in gamm. I am using gamm because I want to test a model
with an AR(1) error structure, and it is my understanding neither gam
nor gamm4 will do the latter.
The data set includes nine short interrupted time series (single case
designs in education, sometimes called N-of-1 trials in medicine)

edf's higher than 1
Simon, in your recent reply to me, you noted that EDF=1 corresponds to a
straight line fit. Does the edf always indicate the polynomial exponent
directly? We ask because Hothorn and Everitt said "Roughly, the
complexity of a cubic spline is about the same as a polynomial of degree
one less than the degrees of freedom." Sorry we attributed the latter to
you, by the way. Will

mgcv gam modeling trend variation over cases
Dear R-Helpers,
I posted two days ago on testing significance of random effects in mgcv,
but realize I did not make my overall purpose clear. I have a series of
N short time series, where N might range from 3-10 and short means a
median of 20 time points. The sample data below (PCP) has N = 4 cases
with 9, 13, 16 and 16 observations over time respectively. The data set
contains four

curve comparison
Dear R users,
I have seven regression lines I´d like to compare, in order to find out if
these are significatively different. The main problem is that these are
curves, non normal, non homogeneous data, I´ve tried to linearize them but
it has not worked. So I´d like to know if you know any command or source in
R which explains how to perform this kind of comparison.
Thanks in advance for your

"DNS update failed" during ads join
I received the warning "DNS updated failed!" during net join. Is this
an important warning? Will there be problems?
Immediately after the join, clients using smbclient were able to
authenticate and access shares on this server - even though "net ads
testjoin" complained about kerberos problems.

re: R-1.9.1 preferences (PR#7170)
okay, so checking the "override" box at the bottom of the menu allows
the changes to take effect.
I still don't understand why you need to have the "override" box there
in the first place

Search Engine (PR#2813)
Full_Name: Anthony Westerling
Version: 1.7.0
OS: Mac OS X 10.2.5
Submission from: (NULL) (64.203.9.4)
R includes a very nice search engine web page which installs at
/usr/local/lib/R/doc/html/search/SearchEngine.html. The search engine and
keywords links do not work on my Mac G4s running OS X 10.2.5, and this appears
to be independent of choice of browser. This appears to be a Mac-specific

R-2.0.1 reinstall non-CRAN pkg
I am trying to upgrade to R-2.0.1 from R-1.9 on a Mac running OS X 10.3.
I have some simple packages I wrote myself that have to be reinstalled
to be recognized as valid packages. I have been using them for a while
on earlier versions of R, so didn't expect to have any problems.
I am probably going about this the wrong way? I simply used
R CMD build mypkgdir
and then
R CMD install

Cocoa GUI: pasting in R Console yields syntax error
I've recently upgraded to R-2.0.1 on a Mac running OS X 10.3+
I am using the new Cocoa-based GUI. Everything was working well for a
while. In the middle of an R session, I started "suddenly" to have a
problem where code copied from an open editor window and pasted into
the R Console gives a syntax error. It doesn't matter what the code
is. If the same exact text is typed

question about dovecot imap outlook clients
Hello,
Well... thanks to the input of all of you I have my dovecot->ldap
connection working for almost all of my clients, however...
on outlook, a message for certificates being trusted comes up, the user
clicks yes and connection fails.
Questions:
Do I have to get an ssl certificate to make it work? ( cost ouch!)
Is there a way around this using my own self-signed certificates?
Is there

RDA and trend surface regression
Dear all,
I'm performing RDA on plant presence/absence data, constrained by
geographical locations. I'd like to constrain the RDA by the "extended
matrix of geographical coordinates" -ie the matrix of geographical
coordinates completed by adding all terms of a cubic trend surface
regression- .
This is the command I use (package vegan):

Hello,
I have recently started learning RoR. I think it''s _fantastic_. I am

OK, this is to prepare you to my idiotic question. Hopefully, I won''t
be stoned.
I am designing a simple application, where users can register, and:

* Determine their list of friends and foes

write fixed format
Dear R users;
Is there a function in R that I can put "text" with proper alignments in
a fixed format. For instance, if I have three fields: A, B and C, where
both A and C are text with 3 characters and left alignment; B is a
numeric one with 2 decimals and 3 integer space digits. How can I put
the following row in a file? (note there is a space between a and 2, and
after b.)

interesting note - not sure just how to take care of this one
Hello all,
the dovecot -> ldap connection is working correctly but I notice
something in my maillog that is disturbing:
dovecot.conf in the passdb section I have
passdb passwd {

then it drops down into the ldap stuff.
The user gets validated via this first and if it fails passes on to the
ldap stuff.
the problem is:
