R-users, Has anyone implemented (coded) the Rai and Van Ryzin dose-response model from their 1985 Biometrics paper. I'm trying to avoid re-inventing the wheel. If not any hints on coding this would be greatly appreciated. Thanks, -- ==================== Calvin L. Williams, Ph.D. ==================== Department of Mathematical Sciences, Clemson University

R-Users, I'm in the process of developing some notes on optimizing likelihoods for a class I'm teaching next term. Can anyone offer examples showing the optimization of a complex likelihood function that they wouldn't mind sharing using optim(). I've adapted some of the S-plus likelihood examplesfrom the ``Guide to Statistics" and the Zip example from ``Statistical Models in

Trying to set up wireless networking with CentOS 4.4 on a (new Dell) laptop and have looked at http://www.ces.clemson.edu/linux/fc2- ipw2200.shtml and http://www.centos.org/modules/newbb/viewtopic.php? topic_id=2532&forum=30 regarding use of ipw2200, which is included in the kernel. The problem is that it doesn't appear to be actually installed/loaded because the Intel Corporation

I have been *manually* dealing with my wired and wireless network interfaces on my laptop. I have a pair of config files (in /etc/sysconfig/network-scripts/: ifcfg-eth0 (wired: Intel Corporation 82540EP Gigabit Ethernet Controller (Mobile)) and ifcfg-eth1 (wireless: Intel Corporation PRO/Wireless LAN 2100 3B Mini PCI Adapter), both with USERCTL=true (and ifcfg-eth0 also has ONBOOT=true).

It gives -1.797693e+308 for any negative arguments. For example, digamma(-1.1) gives -1.797693e+308. The right answer should be 10.15416 This bug can be easily fixed by using the following digamma identity. digamma(x) = digamma(1-x) -

I would like to be able to have the system on the UNIX box be able to read the files on Windows

I am still fairly new to R and have a fairly rudimentary question. I am trying to name a vector of coefficients retrieved from a multilevel model using the coef function. I guess the default name is "Intercept" and I cannot figure out how to rename it. I have tried the using the code below to name the column of coefficients ind.y derived from an lme model. Unfortunately, the

Hello All: I am very new to R and am trying to import some (107) text files into R while simultaneously manipulating the data into a structure that I can use. Below is a description of what I am trying to ultimately accomplish. However, I find that I am unable to even read one file into R using the read.table function. I get the following error: > test<-read.table("test4.txt")

Hello everyone! It has been a while since the 1.0.7 release, and I have fixed a lot of stuff since then. I think it's about time to make another release. I realize that there are still some outstanding issues, but it's nearly impossible to bring that down to zero. However, I'm open to discussion on anything that someone may feel is a "show-stopper". I am on IRC as
