Error: could not find function "lmList"
Dear colleges,
I would like to use the lmList function. I have installed the lme4 library but when I try to use the lmList function I get this error message.
Error: could not find function "lmList"
Here you can see what kind of messages I am getting when installing lme4 package. Does anyone know how to solve this problem?
Thanks

multiple GLMs with lmList in lme4
I'd like to fit a GLM to each of a number of subsets of some data. The `family' argument to `lmList' (in lme4) has given me cause for optimism, but so far I've only been able to achieve linear model fits. For example
> df <- data.frame(gp = gp.temp <- factor(rep(1:3, each = 100)),
x = x.temp <- rnorm(300),
y = rpois(300, exp((-1:1)[gp.temp] + x.temp)))
Then a call to

error in plot.lmList
Hello,
in R-2.1.0 I'm trying to prodice trellis plots from an lmList object as described in the help for plot.lmList. I can generate the plots from the help, but on my own data plotting fails with an error message that I cannot interpret (please see below). Any hints are greatly appreciapted.
kind regards,

[R ] Query : problems with the arithmetic operator "^" with function "lme" and "lmList"
Dear all,
I've got a problem in including square variables in lme and lmlist
functions. I've tried to work on Oxboys data of Pinheiro and
Bates'book, which consist of the heights of 26 boys, each mesured on
nine different occasions :
> Oxboys
Grouped Data: height ~ age | Subject
Subject age height Occasion
1 1 -1.0000 140.50 1
2 1 -0.7479 143.40

[R ] Query : problems with the arithmetic operator "^" wi th function "lme" and "lmList"
Dear Martin,
Have you try to create a new variable for age squared, say agesq? If you fit
the model using this new variable you should get the coefficients. So your
new model is something like height~age+agesq
I hope this helps,
Saghir

sorting in lmList object
Hi all,
Forgive me if this is an obvious one....
I want to make a plot of confidence intervals from an lmList object with a
collection of simple linear models (lm(y~x)) using:
plot(intervals(mylmList))
and sort the plot by increasing mean values for the intercept. Is there an easy
way of doing this? I've tried the "order()" and "sort.list()" functions, but I

subset arg lmList
I'm having trouble understanding how functions in the subset argument for
lmList search for the objects they need. This trivial example produces
"Error in rownames(fakedf) : Object "fakedf" not found":

fakedf <- data.frame(ID = gl(5, 10, 50),

lmList, tapply() and lm()
Howdee,
*** I know that the lmList() function exists, yet I don't want to use it.
***
Would anyone be kind enough to tell how I can apply the function lm() to
each level of a given factor so to obtain the intercept and slope for each
factor level within a matrix?
For instance, suppose a dataframe containing 3 variables: id, x and y.
I want to compute the function lm() for each level

columns corresponding to continuous variables as well as treatment
variables taken on several years and several sites. Here is an example :

possible bug in plot.intervals.lmList
Dear R-devel members,
I think I've found a minor bug in plot.intervals.lmList. ( The guide
https://www.r-project.org/bugs.html suggests to report it here, as I
do not have a bugzilla account.)
Here is a minimal reproducible example to demonstrate the problem:

This results in: "Error in

lmList and lapply(... lm) different std. errors
Am I trying to perform multiple linear regressions on each 'VARIABLE2'. I
figured out that there are different ways, using the following code: (data
is given at the end of this message)
reg <- lapply(split(TRY, VARIABLE2), function(X){lm(X2 ~ X3, data=X)})
lapply(reg, summary)
Which produces the following:

Selecting a random sample for lmList()

Here is the code I have used so far.

Why does lmList() fail when lm() doesn't?
Dear r-helpers,
Can anyone suggest why lm() doesn't complain here:

whereas in package:nlme (and in package:lme4)
osss.lmL <- lmList(logOdds ~ c.setSize %in% task | subj, data = osss)
