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, This may be a simple problem, but I don't have an intuition of how simple it could be. Suppose I have a sequence of numbers corresponding to a series of diagnoses on the same patient over a sequence of time. The diagnoses are coded 1,2,3,4,5, but could come in a sequence like 1,3,2,5,3,5,...etc. Is there a simple way to count the number of times a 1 diagnosis is followed by a 2, or a

Hello. I came across your response in an R forum and could use your help. I have a data set with 472 rows. I want to delete rows 416 through 472. The name of my data set is MERGE. I am an extreme R novice. How do I write a script to accomplish this? Thank you. --- Christopher H. Porter, M.A., M.Ed.

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). I have

I'm new to SAMBA and am somewhat confused. So I'll get right to the point. Situation: I am running both UNIX (Solaris 9) and Windows 2000. I have a system running on Windows will be creating some large files. These files need to be input to a system running on the UNIX (Solaris) box. Solution? I would like to be able to have the system on the UNIX box be able to read the files on Windows

Looking for recommendations.... On WinXP, I use MusicMatch Jukebox version 9 for all my tinkering with mp3s. What do you guys use that would match the functionality of MMJB? I'm mainly interested in the music library setup of MMJB... -- --- David Woyciesjes

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")

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

Hi. I am very new to R and have been diligently working my way through the manual and various tutorials. I am now trying to work with some of my own data and have encountered a problem that I need to fix. I have a dataframe with 8 columns and approximately 850 rows. I have provided an excerpt of the dataframe below. Within column 6 (Question) the numbers 1:33 repeat down the entire column.

Hello all- I am doing a survival analysis for two species of invasive plants I outplanted to edges and interiors of island and mainland sites in a local reservoir.

Hi, I need to ask a question about the usuage of these particular packages...do you install the binaries for each or do you use what comes with the OS out of the box??? The reason why I am asking is because I am having problems using the one that comes with the OS. Everything else runs great but I am using CentOS for the first time and I want to make sure that I am not spinning my wheels

Dear all, I am "still" fairly new to R and newer still to linux (opensuse).

Hello all, Ok, so all this talk has prompted my group to consider installing a firewall. It looks like the most economical approach would be to drop in a machine running linux between our router and our switch to perform this function. We have a 100Mbit full duplex connection here (to other routers on campus), so we would like to be able to pump data through the firewall at this rate. Is
