HI, Using c11<- 0.01 c12<- 0.01 c1<- 0.10 c2<- 0.10 One possible problem is that: dim(res5) #[1] 513? 20 res6<-aggregate(.~m1+n1+m+n,data=res5[,c(1:6,9:12,21:24)] ,max) #Error in `[.data.frame`(res5, , c(1:6, 9:12, 21:24)) : ?# undefined columns selected A.K. ________________________________ From: Joanna Zhang <zjoanna2013 at gmail.com> To: arun <smartpink111 at

Dear R colleagues: Am trying to fit a simple NL model to determine Economical Optimum Nitrogen Rates. The segmented (quadratic + plateau) model only works with some y's, in some cases I get a "singular gradient" error. I'll appreciate any ideas in how to solve the singular gradient error. Thanks, Jose # The following code works using yield2 in the nls model but not using

Hi all, I want to fit data called "metal" with a polynominal function as dP ~ a.0 + a.1 * U0 + a.2 * U0^2 + a.3 * U0^3 + a.4 * U0^4 The data set includes, the independant variable U0 and the dependant variable dP. I've seen that the combination of lm() and poly() can do that instead of using the nls() function. But I don't get how to interpret the results from the linear

Hello R-help, Thanks for everyone's very helpful suggestions so far. I am now trying to use aregImpute for my missing data imputation. Here are the code and error messages. Any suggestions would be very much appreciated.

Hello, Does anyone have experience using a 3ware 9650SE series raid controller on CentOS 6.0? I am getting very sporadic throughput with moderately sized files (0.5-2GB) on ext3. I have tried most of the mount time tuning options: * noatime * trying different journal types * setting commit=120 - helped a little Even after these optimizations it doesn't seem like the raid array is working

Hello there, I am using nlme() to fit a logistic mixed effect model on our data. The outcome variable is binary. I got the error when I wanted to add a group factor to my model. My initial model is as below: model.a <- nlme(response~ 1/(1 + exp( -intercept- u0 - slope*TIME - u1*TIME)), + fixed=intercept+slope~1, random= u0+u1~1 |studentID,

Hello, I'm having an odd problem that I can't find a resolution to. I have a Freebsd 6.2 server with recently upgrade samba software (from 3.0.26a) and an WinXP client. There's a single file: 1015280 -rw-r--r-- 1 userid staff 991M Jan 7 09:13 fbsdusb.img shared from \\server\tmp, that appears twice when browsed from WinXP. If I rename it (i.e. fbsdUSB.img or fbsdusb.iso) or

I use sieve-filter for postprocessing misclassified mail. For false positives I use the following script: require [ "variables", "include", "fileinto" ]; global [ "FORCENOSPAM", "ext", "ext1" ]; set "FORCENOSPAM" "YES"; fileinto "JUNK-PRENOUCE"; if header :matches "Delivered-To"

Dear R-Users, I am looking for a help to deal with the following computational problem: I have a mapping f(x, y) -> (u, v) of [0,1]*[0,1] -> R^2. The mapping is given by tabulating f(x,y) on a uniform 2D grid and is assumed to be "interpolatable" in between the grid points (the number of points on each dimension is rather small, say 5). My ultimate goal is to numerically maximize

Does anyone have, or know of, some S or R code to implement the sequential t-test ? The test is outlined in Kendall & Stuart vol 2A, ch 24, and a 'how to do it' with a set of tables is given in 'Design & Analysis of Industrial Experiments' ( O.L.Davies). I'm interested in obtaining/creating an Splus or R application which calculates the upper and lower curves

prep for 2.8: scopes and variables: nodes are not classes I have been preparing for 2.8 by experimenting with 2.7.X and seeing what it takes to get rid of the warnings. I would like to share my results in a number of upcoming posts. Begin with the simple question of hard-wiring scopes. the ''shocking'' revelation is that variables defined in nodes are no longer visible

I'm hoping that this is a relatively easy question for someone familiar with the lme4 package. I'm accustomed to using HLM software and writing a simple 2 level [null] equation like this: L1 - Yij = b0 + e L2 - b0 = B00 + u0 The following command in R provides results that are identical to the HLM program. results <- lmer( Y ~ 1 |id , PanelData4) I can't
