I have 3 variables relating to the successful introductions of species to 95 different areas: introduction frequency; number of successes pre 1906; number of successes post 1906 The data are not normal, nor homo-skedatic, so I am using non-parametric statistics. I have calculated Kendall's tau between both introduction & successes pre 1906 (tau=0.3903) and introduction & successes

Hello. Please forgive me if this problem has already been posted (and solved) by someone else ... I can't find it anywhere though it seems so very basic. Here it is: I have a list comprised of several matrices, each of which has two columns. > list [[1]] [,1] [,2] [1,] 1 3 [2,] 2 4 [[2]] [,1] [,2] [1,] 5 7 [2,] 6 8 [[3]] [,1] [,2]

Hello, I'm trying to test my data for normality. I enter the data (95ish species counts) run >ks.test (data,pnorm) and get a p- value <2.2e-16 But this seems to be the p-value no matter what the data I enter. (I have multiple datasets and am testing them all for normality). [Actually, I just entered a vector of 1's and the p-value changed.] When I use the >Shapiro.test command,

Hi all, I'm having a problem with the auto.key function in xyplot. I hate to bother the list like this and I'm positive I must be missing something very simple, yet I've spent the last day searching for a solution to no avail. Essentially, I want a key that contains entries in which the plot points are superimposed on a line of the same color as the points, like this: o--o--o Now,

I am getting several errors about Windows only packages when I use task views. Is this suppose to be a Windows-centric utility? Also, I am sure there must be a simple way to tell which packages are in a view, but I haven't found it. If there isn't, it would be nice to have.

Hello, Why the correlation between the random effects is negative? library(coxme) rats1 <- coxme(Surv(time, status) ~ (1|litter), rats) random.effects(rats1)[[1]] #one value for each of the 50 litters print(rats1) rats2 <- lmekin(time ~ (1|litter), rats) fixed.effects(rats2) random.effects(rats2)[[1]] #one value for each of the 50 litters print(rats2)

Hi, I am trying to use the mimR Package. According to its help pages it needs the RDCOMClient package to run. When I try to evaluate a model I get > m.sat<-mim("..",data=gm.dat) Error in mim.cmd("clear; clear output") : couldn't find function "COMCreate" > m2.sat<-emfit(m.sat) Error in toMIM(mim$data) : Object "m.sat" not found >

Dear List, Can anyone please explain the difference between cluster() and frailty() in a coxph? I am a bit puzzled about it.

Hello everyone, I will like to know if there is an R package to compute exact confidence intervals for the ratio of two binomial proportions. Tony. [[alternative HTML version deleted]]

Dear friends - We have 25 rats, 14 of these subjected to partial removal of kidney tissue, 11 to sham operation, and then followed for 6 weeks. So far we have data on 26 urine metabolites measured by NMR 7 times during the observation. I have smoothed the measurements by b.splines in fda including a roughness penalty, and inspecting the mean curves for nephrectomized and sham animals indicate

OK, my journey to make lab machines automagically install & update all desirable R packages is nearing an end! The only question I have now is this: How can I control where the system prints the *.Rout file that is created automatically when the R batch program runs. In "man R" I don't find any information about it. When the cron job runs "R_installAll.sh" (see

Hi, I'm running gam (mgcv version 1.3-29) and glm (logit) (stats R 2.61) on the same models/data, and I got error messages for the gam() model and warnings for the glm() model. R-help suggested that the glm() warning messages are due to the model perfectly predicting binary output. Perhaps the model overfits the data? I inspected my data and it was not immediately obvious to me (though I

Hello R-helpers! I am new to R, but having a rough time with the socketConnection function. I cannot seem to get bi-directional communication to work. I have tried loads of possible ways, based on the manual's examples, but the result is always one or the other process hanging. Could anyone give me a working example of R code that: - creates a socket, - listens for data , - reads the data, -

Dear all, During my pre-R era I tried (yes, tried) to understand mixed models by working through the 'rat example' in Sokal and Rohlfs Biometry (2000) 3ed p 288-292. The same example was later used by Crawley (2002) in his Statistical Computing p 363-373 and I have seen the same data being used elsewhere in the litterature. Because this example is so thoroughly described, I thought

Dear R-users, I am trying to analyse the data of the box 10.5 in the Biometry from Sokal and Rohlf (2001) using R. This is a three-level nested anova with equal sample size : 3 different treatments are compared ; 2 rats (coded 1 or 2) / treatment are studied ; 3 preparations (coded 1, 2 or 3) / rats are available ; 2 readings of the glycogen content / preparations are realised. Treatment is

I keep finding more and more ruby/rails training demo''s. it is pretty awesome. while a video is nice, it is hard if you have to take notes. and some are out-dated. but it is really cool there are so many. on NETBEANS, i just saw this one. and it is recent.
