Best method for comparing rectangles sections of beach
Hi R-listers,
I am trying to compare sections of the beach separated from the HTL to the
Veg (east to west), separated into indices (-5 to 30m), HTLIndex. Cross
parallel (north to south) are major beach sections (Rayos 1, 2, 3, 4 and
MNB). I am thinking to do an ANOVA for each independent rectangle of beach
(not exactly but will be treated as). The HTL from (0-5m) in Rayo 1 is one
rectangle of

Hi R-listers,
I am trying to make a trellis boxplot with the HSuccess (y-axis) in each
Rayos (beach sections) (x-axis), for each Aeventexhumed (A, B, C) - nesting
event. I am not able to do so and keep receiving:

aov() usage
Hi R-listers,
I am wondering if the function aov() in plyr is appropriate for two
different types of tests:
1) > summary(aov(EDI ~ VegIndex, data=data.to.analyze))
AND
2) > summary(aov(HSuccess ~ VegIndex + Aeventexhumed +
VegIndex:Aeventexhumed, data=data.to.analyze))
the later inclusive of an interaction of the two explanatory variables.
This is for obtaining P value and F

Hi R Listers,
I am trying to upload a data file and I received this message. It seems that
I am still able to make graphs and Aeventexhumed still works in the
analysis. Can I ignore this message or do I need to do something about this?

How do I compare 47 GLM models with 1 to 5 interactions and unique combinations?
Hi R-listers,
I have developed 47 GLM models with different combinations of interactions
from 1 variable to 5 variables. I have manually made each model separately
and put them into individual tables (organized by the number of variables)
showing the AIC score. I want to compare all of these models.

Q - scatterplot, plot function & trellis linear regressions???

Q1) What is the difference between the scatterplot and plot function?
Q2) I am able to make a graph with the scatterplot function:

binomial vs quasibinomial
After looking at 48 glm binomial models I decided to try the quasibinomial
with the top model 25 (lowest AIC). To try to account for overdispersion
(residual deviance 2679.7/68 d.f.) After doing so the dispersion factor is
the same for the quasibinomial and less sectors of the beach were
significant by p-value. While the p-values in the binomial were more
significant for each section of the

Clusteranalysis Chi-square test and SingleLinkage
Hi
The short version of my questions is this:
How can I run a chi-square test over a matrix (table) to get the distanaces
between rows and then run a SingleLinkage (or other fusion algorithm over
the resulting table?
