I am a novice R user, and have been in trouble to get the right mixed model syntax in microarray analyses. There are three factors: Dye(2 levels), Temperature(3 levels) and Array(3 for each Temperature with a total of 9 arrays). I want to treat array as random, and to regard array variation different between Temperatures. So the model I want to seek is: Y = Dye + Temp + Dye + Temp*Dye +

Hello R-users, I am currently trying to learn how to use the function gls of the nlme library. I fitted the following model: Generalized least squares fit by REML Model: response ~ array + dye + genes + variety + variety * genes + array * genes + dye * genes Data: data I have 11 arrays, 2 dyes, 2 varieties, 3200 genes, and 2 replications for each. Therefore I should have the corresponding

Hi all, when i run this script: >read.table("Angelika.txt",header=T,sep="\t") >mytable=read.table("Angelika.txt",header=T,sep="\t") >for ( dye in c("A","B","C","F","G","K","L","M")) + { + for (cond in 1:8) + { + measurement =

Given two numeric vectors of possibly unequal length, I'd like to pair each element of the shorter vector with an element of the longer vector such that the sum of squared differences between the pairs is minimized. Can someone point me to an R function or an algorithm for accomplishing this? All the best, Tom Thomas S. Dye, Ph.D. T. S. Dye & Colleagues, Archaeologists, Inc.

Aloha all, I love using ggplot. It took a while to get used to the grammar of graphics, but it is starting to get easy now that I am thinking in a more structured way. A question. I'm making a wind rose that I'd like to be oriented with due north straight up. I've discovered that the orientation is sensitive to how north is represented. When north is represented as 0,

hi all got a windows 2008 server using samba as a primary domain controller. also got terminal services on the windows box for remote desktops, got some clients set up with thinstation to automatically connect to the terminal server with rdesktop. got a problem with logging on and off, its taking about 2 minutes to log in, "please wait for the user profile service", time increases if

Aloha all, I have a data frame with 4 columns. The first three are factors (f1, f2, f3) and the fourth is numeric. I'd like to explore these data using median polish. To do that I plan to use medpolish() on the matrix[f1,f2xf3], then medpolish on the resulting matrix[f2,f3]. This approach is described by Cook on page 141 of Exploring Data Tables, Trends, and Shapes. split()

Aloha all, I have an adjacency matrix for an acyclic digraph that contains transitive relations, e.g. (u,v), (v,w), (u,w). I want a DAG with only intransitive relations. Can someone point me to an R function that will take my adjacency matrix and give me back one with only intransitive relations? In the example, I'd like to get rid of (u,w) and keep (u,v) and (v,w). All the best, Tom --

Hi, I have the following linear mixed model: y(g,i,j,k,l)=u + L(g) + T(i) + D(j) + S(k) + (TS)(i,k) + error(g,i,j,k,l) where S(k) and the combined effect (TS)(i,k) are random effects whereas the rest are fixed effects. How do I specifiy the random part of the model formula in lme(), especially concerning the combined effect (TS)? Moreover, when I run the model as a fixed effect model I get

Greetings, I have a service running on a Windows Server 2003 box that I want to write to a Samba share running on Solaris 10. The Samba is not a DC. How can I give access to the Local System user on the Windows box without making the share writeable to any other user or system?

I have a customer that is using 250 gig drives for his business data. I have been using rsync to keep mirror copies of his data on a second machine. In the last 3 months I have lost 2 of four drives, the last one being the system drive. I have been doing a manual switchover. Each time rsync runs, I copy my samba conf files, passwd, shadow and group files from etc. Has anyone setup a HA

I have been setting up my domain server using FC2 and samba 3.0.9. First thing, for your information: In the notations in several sources, it tells you to user "logon path = \\%L\profiles\%u" this is wrong. It should be, "logon path = \\%L\profiles\%U". Now that I spent 5 million hours banging my head on a wall with that, how do I get he exist desktops on my 2000/XP

Recently I started noticing that after running for a while puppetmaster would freeze after a client called `freshness` which would eventually result in the client getting a timeout and the client dyeing. I tracked the freeze down to the call to ActiveRecord::Base.verify_active_connections! in rails.rb on line 26. After scouring the nets I finally found: http://groups.google.com/group/activemessaging-discuss/browse_thread/thread/7cbbcd761fcb0fd8 which led me to the mongrel faq: http://mongrel.r...

Dear all, I have a performance problem in terms of computing time. I estimate mixed models on a fairly large number of subgroups (10000) using lme(.) within the by(.) function and it takes hours to do the calculation on a fast notebook under Windows. I suspect by(.) to be a poor implementation for doing individual analysis on subgroups. Is there an alternative and more efficient way for doing

Hello, I use lme4 package. library(lme4) fit=lmer(y ~ time+dye+trt+trt:time + (1|rep), data=dataset, na.action='na.omit') anova(fit) The anova gives sequential F-tests and sequential SS. My question is: how I can get partial F-tests and partial SS? For lm (not lmer) anova(lm(y~x+z)) we can use anova(fit, ssType=3) but it is not work for lmer. Natalia.

Dear R helpers, I am working with R 2.4.1 GUI 1.18 (4038) for MacOSX.
