temporal and spatial correlation structures in GAMM
...model the probability that a forest carnivore might have in be located in a
tree hollow (1) (the main resting site selected) rather than elsewhere (0)
(other resting site types, dens, nests, etc.).
The model
should be related with several variables such as for instance:
SHRUB_CV –
shrub cover;
D_RIPARIAN
– distance to riparian habitats
FOREST_PP –
forest habitat (tree availability) proportion in each sampling unit (1 km
buffer around each resting site)
D_RIP_KM –
distance to the nearest riparian habitat..
Day – day

My data
consist of a daily resting site monitoring of 21 animals (dur...

CCA Plot
I am a beginner with R and have managed to use vegan to run a CCA on
my data. I am evaluating the habitat relationships of select species
in riparian areas around creeks before and after logging across three
sampling intervals (pre-logging, two-years post-logging,. and 10
years post-logging). I sampled from 18 sites of 3 treatments (n = 6
sites for each treatment). When I plot my pre-treatment data, I am
plotting data from all 18 sites and...

Estimating variance components of groups of covariates within regression model
I am interested in estimating the variance components from different groups of
variables in a linear regression.
For example, I want to model dependent variable ?Y? based on six covariates as
follows: (these are land use types measured at three scales for each Y,
"Local", "Riparian", and "Catchment" - these are not nested as there is a
unique area for each Y - and Y is a measure of stream health)
L_F=c(3.36,-0.5,-0.91,1.55,-0.02,-0.91,-0.91,-0.91,-0.07,1.69)
L_W =c(-0.3,-0.3,-0.3,4.55,3.2,-0.3,-0.3,-0.3,8.55,-0.3)
R_A = c(-1.4,-1.06,-1.43,-1.72,-0.78,-1.72,-...

canonical correspondence analysis
Is there an R function that does canonical correspondence analysis. Can
it be done using the VR function corresp()?
If not, how hard it be to write R code to do it? I am a population
biologist with long but patchy programming experience in C, Smalltalk,
Java and other languages.
Thanks,
