The R code is:

Categorical data repeated on time analysis
Hi,
I am trying to analyze a data set when nematodes were killed after a
drug administration.
We have counted the number of nematode died and the number of nematode
survival at three time points.
So, there are 100% died in some plot and could be found zero percent
in another. Then, the data set have a lot of zeros.
I have googled and found a lot of information. Moreover, my data isn't

Repeated measures on a factorial unbalanced in a blocks with split-plot design
Dear all,
I am trying to analyze data from an experiment like this:
Factors:
Hormone - Levels: SH, CH (S = without; C=with; H=Hormone)
Time - Levels: 19/08/09, 04/09/09, 18/09/09, 08/10/09, 20/10/09 (DD/MM/YY)
Nutrition - Levels: Completa, Sem (without)
Macronutrition - Levels: Ca, K, Mg, P, Sem (without)
Time is the measures day. It reflect the days after germination.

Improve lattice XYPLOT graphic
Hi,
How I could improve this graphic?
http://www.divshare.com/download/10754700-f81
I would like to write groups labels in each panel and override the
labels from object.
I am try this code:
xyplot(percentagem.mortos~tempo|trat, data=bio.ens, type="a",
? ? ? auto.key=list(points=FALSE, lines=TRUE, columns=3),
? ? ? ylim=c(0,100),scales = list(x = list(at = c(48, 72, 96), labels

Hi,
I run a maanova analysis and found this message error:
Error in ma.svd(X, 0, 0) : 0 extent dimensions
I did a google search and found this:
\item ma.svd: function to compute the sigular-value decomposition
of a rectangular matrix by using LAPACK routines DEGSVD AND ZGESVD.
\item fdr: function to calculate the adjusted P values for FDR control.

Repeated measures unbalanced in a split-split design
Hi,
I have a experiment with block, plots, sub-plots, and sub-sub-plots
with repeated measures and 3 factors (factorial design) when we have
been observed diameter (mm), high (cm) and leaves number (count).
However, we don't have one treatment in one factor, so, my design is
unbalanced.
On a previous message here, a friend tell me that "It appears to me
that your design is a split-split

Difficult to set a quiet formula in maanova
Hi,
I am trying to run an analysis with the package maanova and I am not
getting success.
I suppose that I am wrong on set up the formula, so the issue may not
be related to R, properly.
I have two varieties of plants (V1 and V2). A group of each ones were
treated and another was not treated. After treatment, in three
different time RNA was collected from treated and from not treated
plants for

Dear list member,
My question is related to input file format to an Anova from car package.
Here is an example of what I did:
My file format is like this (and I dislike the idea that I will need
to recode it):
