Hello, I am not sure what to write in the subject line, but I would like to take a character string that is a variable in a data frame and apply a function that takes a numeric argument to this character string. Here is a simplified example that would solve my problem. Imagine I have my data stored in a data frame. > x1 <- x2 <- x3 <- x4 <- x5 <- rnorm(20,0,1); > data <-

Hello, I have a question about the add1() function and quasilikelihoods for GLMs. I am fitting quasi-Poisson models using glm(, family = quasipoisson). Technically, with the quasilikelihood approach the deviance does not have the interpretation as a likelihood-based measure of sample information. Functions such as stepAIC() cannot be used. The function add1() returns the change in the scaled

Hello, My question concerns model selection, stepAIC(), add1(), and coxph(). In Venables and Ripley (3rd Ed) pp389-390 there is an example of using stepAIC() for the automated selection of a coxph model for VA lung cancer data. A statistics question: Can partial likelihoods be interpreted in the same manner as likelihoods with respect to information based criterion and likelihood ratio tests?

Hello, I am trying to compile some F77 subroutines as shared objects for R on my Mac. --> Mac OS-X Version 10.4.11 (Tiger Intel Mac) I have done this (successfully) before on Sun Solaris and Linux Fedora systems using the following command. > R CMD SHLIB myfile.f I have g77 installed from this page. http://hpc.sourceforge.net/ I am using R 2.8.1, and I have installed all 4 additional

Hi All, I've encountered an issue where tail merging MIs is causing a problem with the post-RA MI scheduler dependency analysis and I'm not sure of the best way to address the problem. In my case, the branch folding pass (lib/CodeGen/BranchFolding.cpp) is merging common code from BB#14 and BB#15 into BB#16. It's clear that there are 4 common instructions (marked with an *) in BB#14

Do you have more than one domain controller? Is this just after rebooting a PC?

hI I have to calculate V statistic for each row of a large dataframe (28000). I can not use multtest package for paired wilcox test. I have been using for loop which are. Is there a way to speed the computation with another method like using apply or tapply? My data set looks like this: 11573_MB 11911_MB 11966_MB 12091_MB 12168_MB 12420_MB................ cg00000292

For example if I run "nginx -t" it would give some details about the configurations i.e. if configuration has some error then which file has the error !

Hello, I am not fluent in computer hardware or software development so I will try to be as precise as I can. I am going to build some R routines to analyze large intraday financial data sets. For this project I think that I need be concerned about R memory limits and good memory management/practices. The following R help page states that the limit on individual objects (a vector) is

Dear R users, I'm having some problems with the stack() and unstack() functions, and wondered if you could help. I have a large data frame (400 rows x 2000 columns), which I need to reduce to a single column of values (and therefore 800000 rows), so that I can use it in other operations (e.g., generating predictions from a GLM object). However, the problem I'm having can be reproduced

Hi, Suppose I've got a matrix, and the first few elements look like "x1 + x3 + x4 + x5 + x1:x3 + x1:x4" "x1 + x2 + x3 + x5 + x1:x2 + x1:x5" "x1 + x3 + x4 + x5 + x1:x3 + x1:x5" and so on (have got terms from x1 ~ x14). If I want to replace all the x1 with i7, all x2 with i14, all x3 with i13, for example. Is there an easy way? I tried to put what I want

Dear R users, I have a data with 1000 variables named "x1", "x2", ..., "x1000", and I want to construct a formula like this format: ~x1+x2+...+x1000+x1:x2+x1:x3+x999:x1000+log(x1)+...+log(x1000) That is: the base variables followed by all interaction terms and all base feature log-transformations. I know I can use several paste functions to construct it. But is

This is a newly installed server running CentOS 4 with all current updates. It's been cruising nicely since installation a week ago until this morning. Then everyting started timing out and the attached messages appeared in the log (this is a short and sanitized extract). Load went sky high. Had to reboot to restore service and all looks happy again now, but if anyone can provide some

Hi, You might need to check library(boot).? I have never used that before.? So, I can't comment much.? It is better to post on R-help list.? I had seen your postings on Nabble in the past.?

hey, Rers in Stata therer is a loop command ` ' which could do the following: forvalue i=1/10 { ?gen?x`i'=expression } this will generate variable: x1,x2,,,,,x10. so, does R have a corresponding one to this? And one more very basic question: after I open a file and modify it, such as generate some new variables and change some old ones, how to use the changed dataset in
