Dear R-users, I computed a simple mixed models which was: mod<-lmer(nb ~ site + (1|patelle),tr) The output was: Linear mixed-effects model fit by REML Formula: nb ~ site + (1 | patelle) Data: tr AIC BIC logLik MLdeviance REMLdeviance 1157.437 1168.686 -574.7184 1164.523 1149.437 Random effects: Groups Name Variance Std.Dev. patelle

Dear all, I get an error message when I run my model and I am not sure what to do about it. I try to determine what factors influence the survival of voles. I use a mixed-model because I have several voles per site (varying from 2 to 19 voles). Here is the model: ### fm5 <-lmer(data=cdrgsaou2, alive~factor(pacut)+factor(agecamp)+factor(sex)+ResCondCorp+(1|factor(cdrgsa ou2$ids)),

Dear all, I ran the following model without any problem previously to the update of lme4: fm2<-lmer(data=NGud,family=poisson, seed~hab*seedtray +(1|site)+(1|site:hab)) I have 25 sites, 2 habitats ("hab") per site, 8 seedtrays per habitat (4 as control, and 4 as treatment), and I'm interested in comparing the number of seed in seedtrays as a function of the treatment and its

Hello alls, I found in the literature a technique that has been evaluated as one of the more robust to assess statistically the significance of the loadings in a PCA: bootstrapping the eigenvector (Jackson, Ecology 1993, 74: 2204-2214; Peres-Neto and al. 2003. Ecology 84:2347-2363). However, I'm not able to transform by myself the following steps into a R program, yet? Can someone could help

Dear All, Is there a function in R which can do a periodogram of Schuster ? Thanks in advance ! Guillaume Blanchet

Hi ! I have installed R-2.7.0 64-bits on a computer where the new Ubuntu version (8.04) was installed. This computer is a 3.2 GHz Dual-core with 2 Gb of RAM. To test how fast (I though !) this machine is, I compared two simple matrix manipulations between Ubuntu and my laptop (a MacBook Pro 2.2 GHz with also 2 Gb of RAM under Mac OS X 10.5.2). By the way, I install the normal version of R

Hey, Just wondering if anyone can let me know what the status of IPv6 support for Asterisk is currently. I see that the branch where development was happening has gone away. I was trying: http://svn.digium.com/svn/asterisk/team/blanchet/v6 Has this branched moved to somewhere else? Cheers! -- Andrew Ruthven, Wellington, New Zealand At work: andrew.ruthven at catalyst.net.nz At home:

Friends, At the first Astricon I was very happy to see Marc Blanchet as one of the attendees. I knew he was one of the IPv6 gurus and wanted someone to show some interest in Asterisk and IPv6. Well, he did not only get interested in it, but started coding on it. The results have been available for quite some time at http://www.asteriskv6.org/ and Marc has tested it at several SIPits for

Hi I got two questions about the nnet function in R. I would be thankful to have an answer. 1) Does the function intrinsically normalize the X and Y matrices before the training, or normalization should be done by the user. 2) I need to understand the $wts matrix. I do imagine that it is a single column transformation of the two matrices of weighs (input to hidden Ninputs+1 x Nodes) and

Hi, I'm trying to ouput to a filled with a fixed precision: eg. if I have data x=c(1.0,1.4,2.0), I want to be able to ouput the following to a file: 1.00000000000000 1.40000000000000 2.00000000000000 I was wondering if there was a function to do this in R? Thanks, Richard Richard Hedger Département de Biologie Université Laval Québec, Canada, G1K 7P4 [[alternative HTML version deleted]]

Hi, I've been experimenting with an IPv4 and IPv6 VoIP setup using SER. I'm using Asterisk for voicemail, etc. but as this only works for IPv4, I had to do a number of tricks to get it going for IPv6 phones. I was wondering whether there is any interest or plans in the pipeline to have Asterisk IPv6-enabled. Any info, especially by the developers out there, would be welcome. Thanks, --

Dear all, First of all, I thank you for the creation of the package. I write this message concerning the write.foreign() function from the foreign package and a bug that I discovered. When we want to save our dataset as a .sas file, the limit of variable names character is 8 by default. In SAS this limit is 32 character and an argument in the function, validvarname, can theorically switch the

Hi, I'm a newbie on * trying to setup an HFC card. I'm locked for many days getting the all-circuits-busy. And no idea what else to look for/how to diagnose. I'm in Spain, I've tried changing many parameters on zapata/zaptelcong with no luck, also NT & TE modes (honsetly, I've no idea what is). Any clue will be very much appreciated! I've installed *@home on my RH9,

In October of last year Marc Blanchet of the Canadian company Viag?nie made a presentation on how he and others had build IPv6 support into Asterisk and furthermore demonstrated that it worked. Marc Blanchet went into some details on how it was done and the amount of work that had gone into it. A question is this connection: When will these additions make their way into the Asterisk mainstream

Pierre Legendre has developed a beta version of a new redundancy analysis package called RdaTest that is available on his web page at the Universit® de Montréal. The test example that is included with the package is based on the example provided in his book (Numerical Ecology, Chapter 11 (Legendre & Legendre 1998)) I have downloaded the package and am attempting to run it so that I might

Hi, I am trying to run the command "forward.sel.par," however I receive the error message: "Error: could not find function 'simpleRDA2'." I have the vegan library loaded. The documentation on "varpart" has not helped me to understand why I cannot call this function. Maybe I am missing something obvious because I am still an 'R' novice. Below is a

Hello! I need help (but who doesn's huh? :-) ) I meant to run one program - Money2000 (no, it is _not_ program from Microsoft) together with samba on linux, but i have problems with oplocks. This program is installed locally on win9x/NT and shares its databases. We tried to place databases on novell, on NT server and on win95 acting as server and everything worked fine. But when we tried

Hi all; I'm trying to model a response variable (Y) from one (and eventually more...) independant left-censored variable (X*) In other words, X* is a random variable with values 0 -> inf. Thus, let c=0 X*= x if x>= c X*= c if x< c Does anyone knows a function or package in [R] enabling to model Y from a censored predictor X*? Thanks for your help! ?tienne ?tienne Boucher

Hi all. I have (another) little question about XP and Samba 3.0b3 acting as PDC. When I press CTRL+ALT+DEL in my XP Client I see the message: ",,, has started session as BOOGERSOFT\Boogerman" (BOOGERSOFT is my domain, and Boogerman is my username). I also see the ",,," in the top of XP's start menu (when using XP's startmenu instead of the "classic" start

Hi all! I just migrated to Samba 3.0. I'm using Spanish Windows clients, and when I create a file with a spanish character in its filename (ie: men?), in Windows Explorer it looks ok, but when I do "ls" in Linux I get something slightly different (ie: men??). This didn't happen in samba 2.x (I was previously using the now missing option charset="iso-8859-1"). I tried
