Dear List, on www.r-project.org, the title says 'The R Project for Statistical Computing'. but what exactly is the definition of statistical computing?

[Env: Win XP] I've just upgraded from R 2.12.2 to R 2.13.1. As part of my upgrade process, I typically install some in-development packages from R-Forge that are not on cran. But for the first time, it doesn't work. e.g., > install.packages("p3d", repos="http://R-Forge.R-project.org") trying URL

Hello dear R-helpers, I'm working with R-2.15.2 on Windows 7 OS. I'm stucked with a merge of two data frames by characters. In each data frame I got two different list of names, that is my main-key to be merged. To figure out what I'm saying, I build up a modified "?merge" example, with errors by purpose: # Data for authors: authors <- data.frame( surname =

Dear Specialists in R, May be somebody has experiment in using pakage for the book Quantitative Risk Management by McNeil? This package is writen in R. I have run this package for fitting the data to Nornal Inverse Gaussian distribution and fased with following problem. > Return<-read.csv("data.csv") > Transpose<-t(Return) > fit.NH(Transpose, case="NIG",

Hello all, I have a client with an older Rails 1.8 app (was recently upgraded from 1.6) and I need to integrate a php site to use the same user login creds. I''m not very versed with Ruby but I think this is the code that encrypts the password. [code] # Encrypts some data with the salt. def self.encrypt(password, salt) Digest::SHA1.hexdigest("--#{salt}--#{password}--")

since upgrading to 1.1.4 (I had been running without issue on a git snapshot), I''m noticing that my filter actions initiated from application.rb seem to be running twice. I created a test rails project with the rspec scaffold and am also seeing the same behavior here too. Adding this code to application.rb: before_filter :foo def foo "foo" end and an example

Dear R users: I'm wondering if it's possible to get the residual correlation matrix when using factanal. Since factanal assumes that the errors are normally distributed and independent (provided the factor model fits the data) this would be useful. Of course you would need to submit the data to the function to get the residuals (not just their correlation matrix), but it should be possible

Full_Name: Edward McNeil Version: 2.5.0 OS: Windows XP Submission from: (NULL) (203.170.234.5) This is a new bug introduced to R2.5.0. Scenario: If one of the data frames to merge contains two variables that have the same name, then the data in first variable (of the same name) is copied to the second variable in the resulting merged data frame. In R2.4.1, the second variable name is

How do you get a device into this new class? I don't know the Linux driver model too well, but to get a device

I am working on a competing risks problem, specifically an analysis of cause-specific mortality. I am familiar with the cmprsk package and have used it before to create cumulative incidence plots. I also came across an old (1998) s-news post from Dr. Terry Therneau describing a way to use coxph to model competing risks. I am re-producing the post at the bottom of this message. I would like to

I would suggest that you make a more thorough search of the R-Archives. (http://finzi.psych.upenn.edu/search.html) If you do you will find this discussion has been had several times and that the type of machine you are running will have an impact upon what you can do. My feeling is that you are going have to knuckle down with the documentation and understand how R works and then when you have

Dear List, As someone who is in the process of trying to migrate from Excel, I'd appreciate any help on this question: I have a data set and want to fit, say, three distributions to it. I would like to create a plot that shows my data points against all three fitted curves (estimated d.f.). Basically, I lookint to creat a plot that looks like the one presented in the attached paper (Figure

I'm not sure if this is the right mailing list. My apologies if I'm sending the question to the wrong mailing list. (The r-packages list moderator suggested using the R-help list.) My question is about the "chickwts" data in the datasets package. According to help(chickwts), the source of the data is ?Anonymous (1948) Biometrika, 35, 214. But this reference seems irrelevant.

Dear all I am trying to compare the performances of several methods using the AUC0.1 and not the whole AUC. (meaning I wanted to compare to AUC's whose x axis only goes to 0.1 not 1) I came to know about the Mcneil Hanley test from Bernardo Rangel Tura and I referred to the original paper for the calculation of "r" which is an argument of the function cROC. I can only find the

Hello, I am making some use of ROC curve analysis. I find much help on the mailing list, and I have used the Area Under the Curve (AUC) functions from the ROC function in the bioconductor project... http://www.bioconductor.org/repository/release1.5/package/Source/ ROC_1.0.13.tar.gz However, I read here... http://www.medcalc.be/manual/mpage06-13b.php "The 95% confidence interval for
