Dear R community, I wrote and someone else helped me type a 5-page R-info in Chinese, covering the most basic information on how to get and install and start using R on Wintel PC. This could serve those not fluent in/intimidated by English but want to start using R. (I met a lot of those in China) <http://www.ms.uky.edu/~mai/ZhongWen.htm> also a MSword version of the same (may print

Dear r-help, I ran output <- lm(formu, data=mydata) I want to look at the condition number (to see if the matrix is near singular). How? Also, I use the function stepAIC from MASS to select models, how can I see the condition numbers in each step? While I am at it. I find a minor bug: R 1.7.1 on window XP, when you copy and paste by click one button, then the input stopped, until you

OK, I am forwarding this to the r-help. In the original message I simply hit reply and I thought I send to ALL r-help list. (apparent not) also I recieved another piece of mail.....about the RNG in Splus 4.0 or later indicating it was modified and getting worse. I only have Splus 3.4 for HP. So I cannot try it. This makes the idea of using the pre-generated RN on CDROM more appealing.. Mai

Hi, I was thinking to ask the University computing Labs here to install R and I was told they need a statement that the software (R) is Y2K compliant. Which I cannot find in CRAN. (in addition to the licensing info). Is it a big issue to put such a statement in R? or this has legal implications that R do not want as a "free" software? If possible I would like to see the statement on

Hello all. I've been attempting to utilize the "survival" pkg ( http://cran.r-project.org/web/packages/survival/index.html), while reading through this guide (http://www.ms.uky.edu/~mai/Rsurv.pdf). I figured working through the guide would be the best way to go, before attempting my own data. I tried to utilize the Kaplain-Meier estimator as shown in the guide:

Dear R-help, > prop.test(9, 137, p=0.066) > prop.test(9, 137, p=0.05) give two different 95% confidence intervals. I thought the confidence interval calculation should be independent of testing calculations (and thus the null hypothesis)? Splus 2000 has similar problems but give slightly different answer. Using R1.3.0 on windows. Mai Zhou

Hi, I'd like to execute simple commands and functions in R through a website, is there any service like this somewhere? I only found http://www.osvisions.com/r-online/ but it does not work (last update 2003) and the links to releated websites only give errors (if I calculate 7+3). Thanks for help & hints, Thomas

Hi, dear R-help, I want to fit a Buckley-James censored regression without intercept. The function bj() inside the Design library have to have an intercept, I try Surv(y,d)~ 0 + x , or -1+x, or x-1, none works. Any suggestions? Is there another BJ() code out there that do not have to have an intercept? Or may be it is easier to modify the bj()? I need the estimator only, no need of var estimate

Dear list, I'm using the brew package to generate a report containing various plots. I wrote a function that creates a plot in png and pdf formats, and outputs a suitable text string to insert the file in the final document using the asciidoc syntax, <% tmp <- 1 makePlot = function(p, name=paste("tmp",tmp,sep=""), width=300) {

Dear list, Did anybody have something like multiroot(), similar to uniroot() only for several varibles/function? I know the difficulty several varibles bring. But for nice functions, it can be useful. We are thinking of writing one....I thought to ask first.

I am not understanding something about generating PNG plots. I have tried several ways to obtain something other than a transparent background, but nothing I've done seems to change the background. For example: dev.print(png, width=800, height=600, bg='red', filename='example.png') which I thought would give a red background, simply gives the same transparent background I
