Hi, I was reading a paper published in JCO "Prediction of risk of distant recurrence using 21-gene recurrence score in node-negative and node-positive postmenopausal patients with breast cancer treated with anastrozole or tamoxifen: a TransATAC study" (ICO 2010 28: 1829). The author uses a method to estimate the 9-year risk of distant recurrence as a function of continuous recurrence

Consider the following: > 20:28[1] 20 21 22 23 24 25 26 27 28> 20:29 [1] 20 21 22 23 24 25 26 27 28 29 It seems that when a vector has 10 elements, it prints out differently than one with 9 (extra space before the opening bracket). I can't see why this is happening. I am writing a manual containing many examples and the misalignment of the [1]'s is visually problematic. For

Hi everyone, I would like to know if it's possible to start the smbd/nmbd daemons from an other HP Unix server. The installation of Samba has been made on a RAID mounted on an other Unix server (the main one). We want to do that because whe need to reduce the working flow in the main server.

I'm trying to import a .sas7bdat dataset into R with sas.get. I'm using Win-7 and SAS 9.2. I have read the following post and did tweak the line (127, incidentally) of code. <http://r.789695.n4.nabble.com/R-Problem-with-sas-get-function-in-Hmisc-td81 4367.html> http://r.789695.n4.nabble.com/R-Problem-with-sas-get-function-in-Hmisc-td814 367.html However, I get the following

I'd like to create a plot similar to this one from Kochanska et al.

When setting up my new machine, I had the surprise to see that "Package 'fUtilities' was removed from the CRAN repository." This is problematic for my work. I use many of its functions, and it will complicate things a lot if other programmers want to use my previous code in the future. Plus, nowhere can I find the justification for its removal. Thanks for any info on this

Hello, I have a problem with the princomp method, it seems stupid but I don't know how to handle it. I have a dataset with some regular data and some outliers. I want to calculate a PCA on the regular data and get the scores for all data, including the outliers. Is this possible on R? Thank you for helping!!! -- View this message in context:

Say I fit a logistic model and want to calculate an odds ratio between 2 sets of predictors. It is easy to obtain the difference in the predicted logodds using the predict() function, and thus get a point-estimate OR. But I can't see how to obtain the confidence interval for such an OR. For example: model <- glm(chd ~age.cat + male + lowed, family=binomial(logit)) pred1 <-

Hi all, Please help on this. We will be teaching epidemiology using opensource software. What are R built-in functions or functions in available packages that are capable of doing these: a) Logistic regression (glm?) b) Conditional logistic regression c) Logistic regression with random effects d) Beta-binomial regression e) Poisson regression f) Weibull regression (eha?) g) Exponential

I''m wrapping up a paper on using Rails in the enterprise for the Fortune 500 company I work for. I''ve done quite a bit of research and I think I can present a pretty compelling argument, however I''m still looking for examples. If you have personal examples or links to web resources I haven''t found, I''d apprecate it. Once the paper is complete it

We''re starting to collect several comments for doc revisions, which is = great. Another existing source of comments and suggestions is the list = archives. Would someone be willing to spend an hour or two to (1) search = the list archives for documentation issues/suggestions, perhaps using = search terms like: docs, documentation, instructions, Quick Start, = samples, etc., and (2)
