Mixture Analysis
Dear all,
Does anyone know if the mixture analysis (i.e : sexual dimorphism, age group,…) can be done with R software ? Thanks for your help

ANCOVA, Ops.factor, singular fit???
I'm trying to perform ANCOVAs in R 1.14, on a Mac OS X, but I can't figure out
what I am doing wrong. Essentially, I'm testing whether a number of
quantitative dental measurements (the response variables in each ANCOVA) show
sexual dimorphism (the sexes are the groups) independently of the animal's size
(the concomitant variable). I have attached a 13-column matrix as a data

nlme: gnls with weights and correlation arguments
Some students of mine are trying to use gnls, the generalized non-linear
least squares function within the nlme library, to study evolutionary
questions where correlations between traits at the species level are
non-independent because of the evolutionary relatedness of the species.
Specifically, they're using a non-linear function (log(sexual dimorphism)

Question about random interactions in MCMCglmm
Hi,
I've been a bit confused by different wyas we specify random effects
in lmer and MCMCglmm i just want to clear something. When I want to
look for intersexual genetic correlations in the trait, is it
equivalent to treat this trait for opposite sexes as separate traits
and include the term idh(trait):animal - to treating this as a single
trait and fitting idh(sex):animal? Do these two ways

How to identify the two largest peaks in a trimodal distribution
Hello all
I'm trying to do a simulation that involves identifying the minimum
point between two peaks of a (usually) bimodal distribution. I can do
this easily if there are only two peaks:
CnBdens<-density(Ys/Xs) #probability density function for ratio of Ys
to Xs
for(p in 1:512) ifelse(CnBdens$y[p]>CnBdens$y[p-1],peak1<-p,break)
#identifies first peak in probability

Error in lmer: asMethod(object) : matrix is not symmetric [1, 2]
Dear R Users,
I am having trouble with lmer. I am looking at recombinant versus non
recombinant individuals. In the response variable recombinant
individuals are coded as 1's and non-recombinant as 0's. I built a model
with 2 fixed factors and 1 random effect. Sex (males/females) is the
first fixed effect and sexual genotype (XY, YY, WX and WY) the second
one. Sexual Genotype is

ANCOVA when you don't know factor levels
Hello people
I am doing some thinking about how to analyse data on dimorphic animals
- where different individuals of the same species have rather different
morphology. An example of this is that some male beetles have large
horns and small wings, and rely on beating the other guys up to get
access to mates, whereas others have smaller horns and larger wings,
and rely on mobility to

ancova help
I am trying to run an ancova and am having trouble setting it up properly.
I have nearly 10,000 measurements of fish length, girth and stage of sexual
development. I am suspicious that the stage of development is affecting the
length (as they get full of eggs they get more round and are more difficult
to measure and measure shorter).
My data looks somethign like this:

superimposing network graphs
Dear all,
I have a undirected network (g), representing all the sexual relationships that ever existed in a model community.
I also have a directed edgelist (e) which is a subset of the edgelist of g. e represents the transmission pathway of HIV.
Now I would like to superimpose the picture of the sexual relationships with arrows in a different colour, to indicate where in the network HIV was

procrustes results affected by order of sites in input file
Dear All,
I am using a Procrustes analysis to compare two NMDS ordinations for the
same set of sites. One ordination is based on fish data, the other is based
on invertebrate data. Ordinations were derived using metaMDS() from the
{vegan} library as follows:
fish.mds<-metaMDS(fish.data, distance="bray", k=3, trymax=100,
wascores=TRUE, trace=TRUE, zero="add")

generating ordered, random decimal fractions
Greetings
How do I do this in R? Checking the Cran site produces a bewildering array
of packages that I can't seem to find to load. Surely the main program has
this function?
Cheers

Singling out observations
Greetings
I am attempting to plot observations of a cave aquatic invertebrate
dating from 1901-2004. I can come up with a nice lattice plot of the eight

to highlight the 0 observations on the plots, i.e., attempts to find it at
the site were unsuccessful. I'd like to be able to highlight these

Easy help with plots, font size
I am trying to make some plots for a poster. Each one needs to be 6 inches by
inches. Right now the fonts are too small and the plots don't read well on
my poster. I am pretty much an R newbie and I can't figure out how to change
the fonts. It would also be nice to know how to specify the size of the plot
and maybe how to save the plots as jpeg files. Any help would be much
appreciated! I
