Dear All user
Hello,
I'm a student and I have some trouble with the experimental
(columns-experiments) design of my project. I use a randomized block design

Function for gruping similar variables?
Hi,
I have a matrix of results of multiple 2x2 chi^2 tests, non-
significant tests are marked as TRUE. Is there a function for grouping
those variables in a similar way LSD.test from agricolae library does?
I reviewed LSD.test's source but it's not helpful for me.
This is my matrix:
[,1] [,2] [,3] [,4] [,5] [,6] [,7]
1 TRUE FALSE TRUE TRUE TRUE FALSE TRUE
2 FALSE TRUE

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

[jobs] postdoc in remote sensing with USDA-ARS
The USDA-Agricultural Research Service, Southeast Watershed Research Unit
in Tifton, GA, is seeking a postdoctoral research associate for a
full-time, 2 year appointment. The research associate will develop,
calibrate, and validate a semi-empirical model for estimating cotton
biomass from fields within the southeastern United States. Model
development will involve the use of optical and radar

you could try ???LSD.test?

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

"less than or equal to" glyph
If i insert \u2264 inside the text, like this
lsd_label <- "LSD (P \u2264 0.05) = "
the result is
"LSD (P = 0.05) = "
instead
"LSD (P ? 0.05) = "
how can i solve this problem?
Thanks.

suggestions for ANOVA which includes the "year" as a factor
Dear R Fundation,
I am a post-doc researcher at the University of Pisa, Italy.
I apologize for my english and I have to tell you in advance that I
am a very beginner with R.
I used R for fitting dose-response curves (drc package) and for an
ordinary ANOVA (one, two or three factors), including the post-hoc
mean comparison (I used the LSD test...).
Now I have to process some simple data on

Converting SAS Code
I have no problem setting up my mixed model, or performing anova or lsmeans
on my model?s outputs. However, performing lsd mean separation is giving me
fits.
So I do not have a problem when using two-way anova model. When using the
code:
fit.yield.add <- lm(data = ryzup, Yield ~ Rep + Nitrogen + Treatment)
LSD.test(fit.yield.add, trt = "Nitrogen", alpha = 0.1, console = TRUE)

Help with setting the y-axis in a plot.
Hi all.
I'm working on an assignment for a psychology class and I am not sure how to
adjust the y-axis so it displays the range: 0, 5, 10, 15
The code below is almost ideal:
lsd = c(3, 5, 13)
mar = c(1, 2, 3)
g_range <- range(0, lsd, mar)
plot(lsd, type="o", col="blue", ylim=g_range,
axes=FALSE, ann=FALSE)

Matrix subscripting to wrap around from end to start of row
Perhaps it is just that I don't even know the correct term to search for,
but I can find nothing that explains how to wrap around from the end to a
start of a row in a matrix.
For example, you have a matrix of 2 years of data, where rows are years, and
columns are months.
month.data = matrix(c(3,4,6,8,12,90,5,14,22, 8), nrow = 2, ncol=5)
I would like to take the average of months 5:1 for

lme-post hoc
Hi all,
I analysed my data with lme and after that I spent a lot of time for
mean separation of treatments (post hoc). But still I couldn’t make
through it. This is my data set and R scripts I tried.

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:
