Hello, I'm running SuSE 9.1 Linux, with Samba 3.04. All of the computers are able to print to this one printer, except for this one computer. I can't seem to resolve the problem, and I'm pretty sure it's not Win XP SP2, because another computer at my workplace has the same exact setup, and is able to print. Any help is really appreciated, thank you. Aizat Faiz Oct 20 12:37:09

Hello everyone. This is a question regarding generation of the concordance index (c index) in R using the function rcorr.cens. In particular about interpretation of its direction and form of the 'predictor'. One of the arguments is a "numeric predictor variable" ( presumably this is just a *single* predictor variable). Say this variable takes numeric...

Dear all, As I said in my previous email I have just upgraded to R 2.14.0 on Windows 7. I have just run the 'coxph' function and notice that a Concordance statistic is produced. Is there any way to extract this information from the output? E.g. can I call the concordance value independently of calling the output? Many thanks, Laura [[alternative HTML version deleted]]

Dear All, I am new to R and am trying to learn how to create functions using R. Below is code which calculates Lin's Concordance Coefficient. After I calculate the coefficient I want to create a scatter plot which annotates the coefficient along with preceding text onto the plot. The below code doesn't seem to work. If I use only the object 'lincc' on the text command it works (but doesn't give me the prece...

...ave data which i would want to assess the degree of agreement between two assays, e.g., to evaluate reproducibility or for inter-rater reliability. I have used the Pearson product-moment correlation coefficient. It looks good ranginging between 0.90 to 0.998. Though this looks good. I am told the Concordance correlation coefficient will give a better picture of how reproducible the assay is. Does any one know how to run such a test using R? If so can you kindly provide the code, and bit of explanations to spruce it up? Thank you Paul

Hi, I have been informed of a bug in the concord package, in that the data files containing the tabulated critical values for Kendall's W are not loaded on the command library(concord). I had assumed that the lines in install.R would correspond to the commands to load data in R, e.g. data(Wcrit01) data(Wcrit05) While these work on the command line, I get the errors: library(concord)

I have two alternative Cox models with C-statistics 0.72 and 0.78. My question is if 0.78 is significantly greater than 0.72. I'm using rcorrp.cens. I cannot find the U statistics in the output of the function. This is the output of the help example: > x1 <- rnorm(400) > x2 <- x1 + rnorm(400) > d.time <- rexp(400) + (x1 - min(x1)) > cens <- runif(400,.5,2) > death

I can''t get past the setup step in Capistrano. I know the paths are correct and I''m using zsh locally (bash on remote), so the shell shouldn''t be a problem. It never asks for the SSH password, even. Any help you could give would be greatly appreciated. Thanks. Kenneth -- => the blog from beyond <= => www.eyeheartzombies.com <=

Dear I estimate a sample selection model using the Clayton copula and Burr and Gaussian marginal. I need to derive ther Kendall'sw tau from the concordance coefficient by integration. I came across a way to do that in R long time ago but cannot find it again. Can somewone tell me what to read and what to use? Thank you. Steven Yen

Dear R-listers, I am an MD and clinical epidemiologist developing a measure of comorbidity severity for patients with liver disease. Having developed my comorbidity score as the linear predictor from a Cox regression model I want to compare the discriminative ability of my comorbidity measure with the "old" comorbidity measure, Charlson's Comorbidity Index. I have nearly 10,000

...are specific to B. The question are the 180 observations that are common between A and B - are these 180 common observations occurring by chance? What test would be appropriate for this scenario. (if my total observations are fixed between two experiments A and B, I could use Cohens kappa for concordance or Chi-square etc. Since the total observations differ between experiments A and B, I dont know what test would be appropriate. I appreciate your help. thanks

Hi R-users, I'm having some problems in using the Hmisc package. I'm estimating a cox ph model and want to test whether the drop in concordance index due to omitting one covariate is significant. I think (but I'm not sure) here are two ways to do that: 1) predict two cox model (the full model and model without the covariate of interest) and estimate the concordance index (i.e. area under the ROC curve) with rcorr.cens for both models,...

...usefulness, while others are less so. I consider the plotrix package one of the former, and so as not to upset too many people, I will use the other package I contributed to CRAN as an example of the latter. When I initially wrote concord, it was intended as a package of functions dealing with concordance and reliability. Okay, but I found Kendall's W so useful that I couldn't help including it, and somehow Page's test of ordered alternatives crept in and invited the Jonckheere test to the party and at that point I realized that I had maybe forty or fifty more or less useful function...

Hi! I have been a moderate user of WINE for a few months and it has worked fairly well for the couple of applications that I have tried to run. My SuSE 8.1 Linux laptop is laid out as / linux (reiserfs) /mnt/win windows c: (vfat32) /mnt/chunk windows d: (vfat32) and I have previously had no problems either running WINE or booting into Win98. I have been able to call my program as
