Crossed random effects in lme
Dear all,
In the SASmixed package there is an example of an analysis of a split-plot experiment. The model is
fm1Semi <- lme( resistance ~ ET * position, data = Semiconductor, random = ~ 1 | Grp)
where Grp in the Semiconductor dataset is defined as ET*Wafer. Is it possible to specify the grouping directly some way, e.g. like
fm1Semi <- lme( resistance ~ ET * position, data =

coding nesting in data for nlme example of Wafer data set.
I am trying to understand the proper way to encode the nesting structure
for data in the context of nlme, in the specific case of individuals
nested within species for which each individual is unique. I have
searched through Pinheiro & Bates and also past postings, but without
success.
Take the Wafer data set which has 2 levels: Wafer (8 values) and Site
nested within Wafer (10 values for

lme syntax for P&B examples
Hi helpeRs,
I've been working through some examples in Pinhiero & Bates( 2000)
trying to understand how to translate to the new Lme4 syntax but without
much luck.
Below is what I think I should do, but either the answers don't come out
the same or I get errors.
In the Oxide problems I'm particularly interested in obtaining the
levels coeficients but this options no longer seems

lmer random effect model matrix question
I have one fixed effect, sor, with two levels. I have eight lots and
three wafers from each lot. I have included the data below.
I would like to fit a mixed model that estimates a covariance parameter
for wafer, which is nested in lot, and two covariance parameters for
lot, one for each level of sor. The following command fits the model
that I want, except for it estimates the correlation

trouble with Vista & reading files
All,
I am having trouble with a "read.table()" function that is inside of
another function. But if I call the function by itself, it works fine.
Moreover, if I run the script on a Mac OS X (with the default Mac OS X
version of R installed, rev 2.8), it works fine. But it does not work if I
run it on windows vista (also default Windows version of R, rev. 2.8).

Question to NLME, ML vs. REML
Dear all,
I am planning to use nlme library for analysis of experiments in semiconductor
industry. Currently I am using "lm" but plan to move to "lme" to handle
within wafer / wafer-to-wafer and lot-to-lot variation correctly.
So far everything is working well, but I have a fundamentel question:
NLME offers "maximum likelihood" and "restricted maximum

Can anyone help me, my R software can not run a nested linear regression by using the lme funcion. The message that appears isĀ

I have created a tree and want to save some of the
data so that I can create a html table from it.
I would like to save the output from data.ltr (see
example below) to a file, but haven't found a way to
do that, keeping the nice format that typing data.ltr
gives me (see output below). Is there a way to do
this?

How to interpret an ANOVA result?
Hello all,
here's a real-world example: I'm measuring a quantity (d) at five
sites (site1 thru site5) on a silicon wafer. There is a clear
site-dependence of the measured value. To find out if this is a
measurement artifact I measured the wafer four times: twice in the
normal position (posN), and twice rotated by 180 degrees (posR). My
data looks like this (full, self-contained code at

Lmer BLUPS: was(lmer multilevel)
Paul:
I may have found the issue (which is similar to your conclusion). I
checked using egsingle in the mlmRev package as these individuals are
strictly nested in this case:
library(mlmRev)
library(nlme)
fm1 <- lme(math ~ year, random=~1|schoolid/childid, egsingle)
fm2 <- lmer(math ~ year +(1|schoolid:childid) + (1|schoolid), egsingle)
Checking the summary of both models, the output is

wafer map drawing
Hello R-Users!
Does anyone know of a package to draw/analyze silicon wafer maps?
Here are some examples

I've google'd and searched CRAN with no luck.
It seems possible for R, given the hexbin and hist2d graphs I saw at the

Trellis Plot Labels
Hello everyone,
I am ploting a groupeddata object with formula:
formula(mydatausegroup)
BF ~ HO | ID/Infar/Day
Using this command:
plot(na.omit(mydatausegroup), displayLevel=2,layout=c(10,2),aspect=2)
This trellis plot does almost what I want and produces a 10x2 trellis plot, each panel is labeled
as ID/Infar where infarct is either 1 or 0. And in each panel, it plots BF vs HO for each Day.

xyplot does not find variable in data
When we call a lattice function such as xyplot, to what extent does
the "data" designation cause the function to look inside the "data"
for variables?
In the examples below, the "subset" argument understands that
"Variety" is a variable in the data.
But the "scales" argument does not understand that "nitro" is a
variable in the data.
