Non-ASCII chars in R code
The report on R_help about problems loading package irr (in a UTF-8 locale, it seemed) prompted me to look a little deeper. There are quite a few packages with Latin-1 chars in their .R files, and a couple in UTF-8. Apart from non-ASCII chars in comments, this is a problem as the code concerned cannot be represented in some locales R runs in (for example Japanese on Windows). It happens

More than two font in a plot
Hi there, I am a Chinese R user. I hope to display Chinese character in a plot, and than save it in PostScript format.

Trying to get gog.com's FALLOUT to run
I use a MacBook Pro running Mac OS X 10.5, and Crossover Games for Mac version 7.2.1. I decided to try an experiment and see if the gog.com version of FALLOUT would work on Crossover Games after reading that it doesn't work in the current version. The difference between the original disk version of FALLOUT AND FALLOUT 2 and the gog.com version is that the people at gog.com have not only

Package or packages for randomization in a clinical trial
Can anyone recommend a package that can be used to randomize subjects? I am looking for a generalized package, or several packages that can accomplish unrestricted randomization (i.e. simple random assignment) restricted randomization including stratified randomization, blocked randomization, and adaptive randomization.

stepwise regression
Dear all, I have encountered a problem when perform stepwise regression. The dataset have more 9 independent variables, but 7 observation. In R, before performing stepwise, a lm object should be given. fm <- lm(y ~ X1 + X2 + X3 + X11 + X22 + X33 + X12 + X13 + X23) However, summary(fm) will give: Residual standard error: NaN on 0 degrees of freedom Multiple R-Squared: 1, Adjusted

Help on hypothesis testing
Hi, I hope to use R to perform some hypothesis testing, such as t.test() and var.test(). However, I don't find a function that could do test on means with variance known (i.e., u test or z test in some textbook), and a function that could do test on variances of normal distribution (i.e. chi-squared test). Thanks in advance for any hints. Best wishes, Jinsong

Help use try function with boot
Hi R users, Is is possible for me to use the try function with boot? I would to do the bootstraping with a nonlinear model(it works well when R < 1000). But it does not work very well (when R is large) thus I try to use "try" to resolve. I put the try function in two cases: case1: put the try in front of the boot > c1.try<-try(boot(c1data, statistic = c1.fun,

SV: Fax to email using mime-contruct
I also want to try that asterisk guide. But i'm not sure if i understood it correctly. What exactly do i need to do? Do i need to compile Asterisk with the spanDSP plugin or just configure extensions.conf? The URL to spanDSP in the guide wasn't working. I also use a traditional internet line to recieve calls and hopefully i will get Fax working soon. This is so confusing. Thanks, Arne
