How to convert a vector into a list
1. When you don't know (or are not sure) what an object is, str() is your friend. 2. My guess is that `lidnames' is a character vector with names. 3. If genes.txt has only only column, you might as well use: mygenes <- scan("genes.txt", what="") which reads the data into mygenes as a character vector. Then your command should work. [read.table()

CKD-Epi formula
Hi all, I have a question and I do not know If I am at the right place to ask this question. But is there someone that has the formula of CKD-Epi in code in R? I have tried a lot of loops, but none of the approaches give me the right answer. Is there someone who has this formula coded? Thank you! [[alternative HTML version deleted]]

linear regression for grouped data
Hi, I have been examining large data and need to do simple linear regression with the data which is grouped based on the values of a particular attribute. For instance, consider three columns : ID, x, y, and I need to regress x on y for each distinct value of ID. Specifically, for the set of data corresponding to each of the 4 values of ID (76,111,121,168) in the below data, I should invoke

Problem of COX model with time dependent covariate

This covariate shows time-varying effect, I add a time-covariate interaction item to build Cox model as follows: COX <- coxph(as.formula("Surv(TIME,outcome)~eGFR_BASE+eGFR_BASE:TIME"),ori.data); coef exp(coef) e(coef) z p eGFR_BASE

Why do methods of "initialize" have no "srcref" attribute as other S4 mehtods?
For documentation we use a system that generates Rd files from special comments in the code. (inlinedocs). It is crucial to be able to get the defining source code for objects like methods to extract the comments from it. Here is an R session that shows how this works for several kinds of methods and (at the end of the session) how if fails for methods of "initialize" >
