Dear All, When I tried to install R packages I found this error: > library(survival) Loading required package: splines > install.packages("splines") --- Please select a CRAN mirror for use in this session --- Warning message: package splines is in use and will not be installed But I just opened R, and have used anything yet, how come did it say "package splines is in

Dear all, I tried to use "step" function to do model selection, but I got an error massage. What I don't understand is that data as data.frame worked well for my other programs, how come I cannot make it run this time. Could you please tell me how I can fix it? ***************************************************************************************************

Greetings R-Helpers: I am trying to help a Chinese colleague who is experiencing difficulty loading my package. He is running WindowsXP and the Chinese version of R2.8.1. As you can see from his screen-copy (below), my package is successfully unpacked but cannot be loaded because splines balks when attempted to be loaded. Package mh1823 requires package survival, which in turn requires

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

I don't use MySQL but I have seen messages like this before. They often have replies which indicate that you need to follow the instructions more closely. I suggest you search the list for these previous posts as I'm sure there is help there, somewhere!

Hi, I'm using natural cubic splines from splines::ns() in survival regression (regressing inter-arrival times of patients to a queue on queue size). The queue size fluctuates between 3600 and 3900. I would like to be able to run predict.survreg() for sizes <3600 and >3900 by assuming that the rate for <3600 is the same as for 3600 and that for >4000 it's the same as for

I have a debugging environment for the survival package, perhaps unique to me, but I find it works very well. To wit, a separate directory with copies of the source code but none of the package accuements of DESCRIPTION, NAMESPACE, etc. This separate space does NOT contain a copy of src/init.c Within this I use R --vanilla, attach my .RData file, survival.so file, and away we go. That is,

I've finally narrowed down a puzzling problem: here is the short test case. tmt34% R --vanilla R version 2.10.0 (2009-10-26) Copyright (C) 2009 The R Foundation for Statistical Computing ISBN 3-900051-07-0 > temp <- matrix(runif(50), ncol=2) > t(temp) %*% temp [,1] [,2] [1,] 7.916016 6.049698 [2,] 6.049698 7.650694 > library(kinship) Loading required package:

I'm puzzled by as.matrix. It appears to work differently for Surv objects.

Dear all, I am wondering if there is a way to find how R defined(or wrote) the function of "coxph"? I don not mean the one that we get by checking help(coxph), but the one like coxph<-function(....){...} Thanks, Jia

I had trouble with some tests for the survival suite last night that I cannot explain. Framework: Ubuntu Linux, R2.11. For testing survival I have a separate directory and Makefile. I pull everything into the local .RData, no packages, library, or namespace. (It's easier to add test modifications to a routine in a chain of calls). A test of survreg + psline would fail because

Hello, I am modeling some survival data wih cph (Design). I have modeled a predictor which showed non linear effect with restricted cubic splines. I would like to retrieve the se(coef) for other, linear, predictors. This is just to make nice LateX tables automatically. I have the coefficients with coef(). How do I do that? Thanks, David Biau.

Hi, I'm running into an error message for the "anova"-function I never got before with the Design (Version 2.2-0) package.

I'm looking for software that makes plots such as fig 4 (a)-(e), fig 5 anf fig 7 of Gray, Robert, "Flexible Methods for Analyzing Survival Data Using Splines, with Applications to Breast Cancer Prognosis," 1992, J Am Stat Assoc, pp 942-51. In other words, I'm looking for software that takes survival data and a continuous covariate as input and computes a curve giving log hazard
