Always cc the list unless there is good reason to keep your reply private.
There is no LSmeans() function in the lsmeans package.

LSmeans and lsmeans
A cursory reading indicates that they are identical; but others more
knowledgeable than I need to confirm or deny this.

how to get "lsmeans"?
Dear all,
I search the mail list about this topic and learn that no simple way is available to get "lsmeans" in R as in SAS.
Dr.John Fox and Dr.Frank E Harrell have given very useful information about "lsmeans" topic.
Dr. Frank E Harrell suggests not to think about lsmeans, just to think about what predicted values wanted
and to use the predict

Regarding point 3, as a moderator I have been helping Andrew get this
post out to the list over the past week. His previous attempts were
encoded in some way that the listserv rejected. He sent me the post via
his gmail account and viewing the source I saw it had at least both
plain test and HTML an I said it was worth a try to post it. Certainly

lsmeans in R
I need help with calculating lsmeans (adjusted means) of different terms in
a linear model including the main effect and the interaction effect terms. I
use lm to run the linear models...I previously noted from literature that
that "effects" package can be used to generate lsmeans. But I tried to use
it but could not figure out which option to use to get means. If anyone can
give an

Converting SAS Code
I will offer an opinion, with which others may fairly take issue.
If you are coming from SAS and wish to learn R, you should forget about SAS
entirely; it is ancient and convoluted. But more to the point, as others
have already suggested, you will only confuse and hamstring yourself trying
to convert the programming paradigms of one language into another. Better
to consider the **tasks** you wish

Imputing missing values using "LSmeans" (i.e., population marginal means) - advice in R?
Hi folks,
I have a dataset that consists of counts over a ~30 year period at multiple (>200) sites. Only one count is conducted at each site in each year; however, not all sites are surveyed in all years. I need to impute the missing values because I need an estimate of the total population size (i.e., sum of counts across all sites) in each year as input to another model.

How to get LSMEANS from linear mixed model?
Hi there,
I am trying to run simulations using R with linear mixed model (lme). There
are two factors in my fixed effect model, educ (treatment and control) and
mth (visit 1, 2, and 3). What I want to obtain is the estimated treatment
difference (treatment - control) at visit 3, plus the standard error and
p-value. This can be easily obtained in SAS using lsmeans or estimate
statements, but I

Dear list,
Is there a function (or an equivalent way) in R resembling the lsmeans
command in SAS? The objective is to get the (adjusted) means for design
models. Thanks in advance.

lsmeans
Hello,
I have the next function call:
lme(fixed=Error ~ Temperature * Tumour ,random = ~1|ID, data=error_DB)
which returns an lme object. I am interested on carrying out some kind
of lsmeans on the data returned, but I cannot find any function to do
this in R. I'have seen the effect() function, but it does not work with
lme objects. Any idea?
Best,
Dani

nested model: lme, aov and LSMeans
I'm working with a nested model (mixed).
I have four factors: Patients, Tissue, sex, and tissue_stage.
Totally I have 10 patients, for each patient, there are 2 tissues
(Cancer vs. Normal).
I think Tissue and sex are fixed. Patient is nested in sex,Tissue is
nested in patient, and tissue_stage is nested in Tissue.
I tried aov and lme as the following,

R-analogue to the estimate and lsmeans statements in SAS
Dear all,
In connection with a stats course where we want to use R, I am trying to find out if there are analogues to the ESTIMATE and LSMEANS ("population" means) statements in SAS (in proc glm, proc genmod and proc mixed). The students are agronomists, vets and that sort of people, and most of them have some familiarity with SAS.
The design package seems to go some of the way, but

means comparison in R (post-hoc test)
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Hi.
I have been using SAS for some time, and now I have discovered R. I am
very happy with it, but I have not found out how to perform some of the
multiple comparisons I was used to do in SAS.
With the SAS/STAT, I generally used the MEANS (for comparison of
arithmetic means) and the LSMEANS (for adjusted means) statements of the
GLM procedure (I

You might get better answers if you
1 - break this down into separate issues
2 - tell us what you want to achieve in words rather than SAS, we all
read English but few of us speak SAS
3 - post in plain text not HTML as HTML mangles your post

confidence intervals for linear combinations when using lme
Hi
I really hope someone can help me.
I have just started to work with S-plus, and have not yet understood how it
really works. I am now trying to fit a mixed effects model with lme. My goal
is to compare four different groups, at several different time points, and I
therefore would like to create confidence intervals for linear combinations
of my estimated parameters (as I usually do with
