No documentation for ?LSD.test? in specified packages and libraries:
you could try ???LSD.test?

The model should be class aov or lm and my model class is aovlist.
tried tidy from broom library but did not work. To make it class aov,
I had to remove the error term;
model <- aov(Rotationdata_R$`GY(Mg/ha)`~Rep+code*as.factor(Nitrogen),data=Rotationdata_R)

Do I need a special package to run LSD tests?
Hi there,
I am trying to run LSD.test(model)
I used the following commands:
attach(model)
m1<- glm(ttl.m ~ site+year, family=quasipoisson, data= model)
df<-df.residual(m1)
MSerror<-deviance(m1)/df
The following command did not work:
comparison<- LSD.test (ttl.m, site+year, df, MSerror, alpha = 0.05,
group=FALSE)
I get an error message: Error: could not find function

Fisher's LSD multiple comparisons in a two-way ANOVA
Hi there,
Is there a function that can do a Fisher's LSD multiple comparisons in a
two-way ANOVA? I hope to get a result similar with TukeyHSD().
Especially, I hope to know the significance of comparisons between the
interactions of two factors.
In the following example:
x <- c(76, 84, 78, 80, 82, 70, 62, 72, 71, 69, 72, 74, 66, 74, 68, 66,

Fwd: Re: LSD multiple comparison test
I am returning this to the R-help list. Please keep followups on the list.
Yes, it can be done. It is not currently easy because multcomp doesn't
have the syntax yet. Making this easy is on Torsten's to-do list for the
multcomp package.
See the MMC.WoodEnergy example in the HH package. The current version on CRAN
is HH_1.17. Please see the discussion of this example in R-help:

Efectos aleatorios, interaccions y SNK, LSD o Tukey a claración de las datos
Hola de nuevo R-Users,
me he dejado cosas para aclara.
Primero de todo tengo cinco repeticiones y 20 missings, así que mi n
es de 5×10×3×5-20= 730 datos en total, todos los grupos tienen al
menos 3 representantes.
Segundo: Las variables estudiadas son Producción neta, Peso de 100
semillas y Proteína.
Tercero: Observo los mismos genotipos (G) en varios años (A) en las
misma localidades

LSD, HSD,...
Hi,
I'm designing a experiment in order to compare the growing of
several clones of a tree specie. It will be a complete randomized block
design. How can I decide what model of mean comparision to choose? LSD,
HSD,TukeyHSD, Duncan,...? Thanks in advance

Efectos aleatorios, interaccions y SNK, LSD o Tukey
Queridos R-users:
Tengo una duda que hace mucho tiempo que estoy intentando resolver, os
explico a modo de ejemplo:
Tengo estos efectos: Año(5 niveles),Localidad (10 niveles) y genotipo
(3 niveles), año y localidad son aleatorios y genotipo es fijo (los he
escogido yo).
Me gustaría hacer obtener una tabla parecida a la Tabla Anova donde
aparezca cada factor y sus interacciones y

R emacs and ess
Hi all,
I want to apologise first for being a beginner with linux/emacs/ess;
I am pretty good with R ;).
I have R-1.9.1 installed on my directory of a linux server, I also have
ess 5.2.8 installed there as well. When I call R using (C-u M-x R) in
emacs, i receive the following error [no match].
I was wondering if emacs is not looking for ess in the right place (if

Non linear regression using Levenberg-Marquardt method
Hello,
I want to fit some non linear models with the Levenberg-Marquardt
algorithm. It doesn''t seem to exist any function to do this in R ( well,
maybe one does, but I''m a new user, and the only documentation I have is
"An introduction to R").
I''d like to know if this function exists, maybe throught an additionnal
package.
I''d also like to know if if

multiple comparisons with generalised least squares
Dear R users,
I have used the following model:
M1 <- gls(Nblad ~ Concentration+Season + Concentration:Season, data=DDD,
weights=varIdent(form=~ 1 | Season*Concentration))
to assess the effect of Concentration and Season on nitrogen uptake by
leaves (Nblad). I accounted for the difference in variance across the factor
levels by using the varIdent function.
Then I wanted to perform multiple

rnorm using vector of means and SDs
Hi,
I want to sample from a distribution (say a normal distribution, for example) using vectors of the different parameters (i.e. the mean and standard deviation). That is, I have a list/vector of say 100 means and another of the corresponding 100 SD's, and I want a matrix of 100 rows (one for each mean and SD pair) each having 1000 random samples.
Something like:

Parámetros iniciales para ajustes no lineales
Hola a todos
estoy aplicando la función polinómica de Hossfeld [1], y algunos otros modelos no lineales para tratar de ajustarlos a un grupo de datos forestales,
[1] Y= b*t*exp(c)/(t*exp(c)+a)
Al colocar la función en R con parámetros estimados, me devuelve los siguiente:
## model1 <- nls(ho ~ (b*edad*exp(c)/(edad*exp(c)+a)), data=nigra,
start=list(a=0.005,b=0.08,c=-0.00006),

I agree, it is great.
I have some regression tests (check-all) failures on Windows locally. Does
the buildbot show the same?

[LLVMdev] Buildbot for Windows native LLVM/Clang testing
Hi All,
This is to let you know that a new buildbot for Windows native LLVM/Clang testing is established:
http://lab.llvm.org:8011/builders/clang-x64-ninja-win7 .
Hardware + OS configuration is: Haswell desktop with Windows 7 + Visual Studio 2013 Update 4.
It is hosted by Intel and hopefully will contribute to improve quality of the LLVM/Clang on Windows being developed in the LLVM community.
