similar to: logistic regression with repeated measures for species-habitat associations

Hello, I'm working with a series (30+) of hydrologic metrics and 10 vegetation communities and I need to determine which of the metrics provide the best separability for each of the vegetation communities. The hydrologic metrics are highly correlated, therefore the need to reduce the number of them considered is critically important. I've been looking at the scatter3d function in the

Hi R users, I am using the following model to analyze data from a factorial experiment (randomized complete block design with no replication within blocks): model <- glm(survival ~ density * vegetation + (1|block), data=sal2005, family="binomial") Does R use a binomial distribution in this formulation to model random effects or a normal distribution (in which case the analysis is

Dear R Professionals, I am currently an intern at the University of Rhode Island and I need to know how to export data from R into an Excel file. As it is my understanding, xlsReadWrite is not available for mac. Is there another package available for mac users to be able to perform this function. Sincerely, Maureen J Hayden University of Rhode Island Class of 2015 Marine Biology Major

(To the list moderator: I just subscribed to the list. Apologies for not having done so longer before trying to post.) Hi all, I am currently using lmer to analyze data from an experiment with a single fixed factor (treatment, 6 levels) and a single random factor (block). I've been trying to follow the online guidance for estimating p-values for parameter estimates on these and other

Hi- I'm a biologist trying to figure out the growth rate of salamanders in different ponds. I collected individuals from various populations at different dates, and using the size and date collected, I want to figure out the growth curve of each population. My question is: How do I fit my data to a Gompertz function in R? Thank you so much! Sarah -- View this message in context:

Hello i did a stacked barplot using ggplot and R arranged the bars of the items in different orders. i don?t know why. but i want to have the same order in every stacked bar. I used the code data1 <- read.table("N_O_W_MAI.txt", header=TRUE, dec = ",") attach(data1) Teich1<-factor(Teich,levels=c(5,7,9,11,"G") ,ordered=is.ordered(Teich))

Hello all, If someone could take a little time to help me then I would be very grateful. I studied piping plovers last summer. I watched each chick within a brood for 5 minutes and recorded behaviour, habitat use and foraging rate. There were two Sites, the first with 4 broods and the second with 3 broods. http://r.789695.n4.nabble.com/file/n4511178/Table_PP_Maslo_et_al.png As the data within a

Dear all, I am trying to fit a generalized linear mixed model to deal with both temporal and spatial pseudorreplication. I have repeated seasonal measurements (3 seasons during 3 years and 2 season during the last year, factor named percod, with 11 levels) of a bird presence/absence (pres.f) on 14 artificial ponds (charca.f). The ponds are integrated in 4 greater spatial units (zepa). I have

Hello, I am having trouble doing a split plot analysis of variance with lme. The study design is ponds split in two, one side of each pond was a control and the other was one of three chemical treatments. Each pond side was sampled three times, response variable is the mean of twenty animals. So we have sample time within side within pond. Pond is random effects. There are three or four

Dear All, I am trying to model the habitat mapping of 4 sharks species and my data are zero inflated and positively skewed. The zero percentages in my data vary between 56-77%. I did some tests fitting GAMs with negative binomial family (with theta between 1-10). Is this the best way to go? Some people have used VGAM (with zero inflated negative binomial) but my concern is that using the VGAM

Hi Helpers: I have a factor object that has 314k entries of 39 land cover types.

I see that "case weights" can be optioned in multinom(). I wanted to make sure I understand what weights= is expecting. My weights (not really mine but I'm stuck with them) are noninteger, are not scaled to sum to the sample size, and larger weights are intended to increase influence. The description of various types of weights is a perennial confusion for me; sorry. STS

The computations done by print.survfit are now a part of the results returned by summary.survfit. See 'table' in the output list of ?summary.survfit. Both call an internal survmean() function to ensure that any future updates stay in

I hate to repost this perennial newbie question, but even after browsing the archives and trying various remedies, I'm still stuck. The problem: I've compiled Wine from Wine-20011226 on Mandrake 8.0, and when I try to run an application, I get the following: $ wine mspaint Loading required GL library /usr/X11R6/lib/libGL.so.1.0 fixme:x11drv:OBM_CreateBitmaps Xpm support not in

Dear R-devel, Apologies for bothering y'all with this seemingly perennial question. A user reported problem with my most recent version of randomForest (4.4-1), and I was able to reproduce it with his data with R-2.0.0 patched (2004-10-24) on WinXP Pro. The problem is that it crashes R on Windows. However, it does not happen on Linux (tried SUSE ES8 on our Opterons and Quantian on my

A bit of a perennial I'm afraid. My wife has filled up her iPhone 6 with photos, and wants them moved onto my computer. I'm running CentOS 7 patched about 30 minutes ago. Needless to say the computer can't see the data on the iPhone, though it does recognise the phone as an iPhone. Any suggestions (well any that don't involve a steam roller, sledge hammer or GBH to the whole of

hi, what''s the best way (if at all) to iterate through all of a domain''s page tables within xen 2.0.6? i need to find all references to a specific pte value (which is a given). essentially, a reverse page-table lookup. i''m hesitant to switch to 3.0, but if it''s easier to do what i want, just let me know. thanks, -A. -- Aaron Marks Distributed Systems Lab
