Making a group membership matrix
Hi Helpers:
I have a factor object that has 314k entries of 39 land cover types.
(This object can be coerced to characters neatly should that be easier
to work with.)

Nested anova with unbalanced design and corrected sample size for spatial autocorrelation
Hello all,
This may be a simple question to answer, but I'm a little bit stumped with
respect to the calculation of the F statistics in nested anovas with
unbalanced design in R.
In my case, I have 11 vegetation transects (with 1000 10cmx10cm squares),
where we estimated shrub cover. We have two different treatments: wildfire
(4 transects) and prescribed burning (7 transects) and we want to

discriminant analysis
Hello.
I have a data base with 50 qualitative variables and a lot of
individuals. I try to estimate the links between one of these variables
(landcover) and the 49 others (geomorphology, hydrography...). I want to
use a "discriminant analysis on qualitative variables" (as DISQUAL in
SPAD) or a " log-linear model ". Which R-Package(s) or other methods can
you advise me.

Problems with lattice plot
Hello useRs,
I have some problems when I try to plot a lattice. The lattice has 200
columns (X value) and 5 rows (Y value), with a total of 1000 squares. I
want to plot this lattice with the squares having different colours
according to a variable value.
The variable I want to plot is cover value of a shrub, and it has values
between 0 and 1. I want to plot the squares with value 1,

Handling realisations in geoRglm
Dear R users:
I want to model mosquito count data based on landcover attributes and
meteorological variables using a Poisson GLSM in the geoRglm package. I
have monthly mosquito counts over more than 20 years with repeated
observations from individual trap sites over time. I have used
as.geodata() to successfully read my dataset into the geodata format
utilized by geoR and geoRglm,

Error message in GAM
Hello useRs!
I have % cover data for different plant species in 300 plots, and I use
the ARCSINE transformation (to deal with % cover data).
When I use a GLM I do not have any problem.
But when I am trying to use a GAM model using mgcv package, to account for
non-linearity I get an ?error message?.
I use the following model:
sp1.gam<-gam(asin(sqrt(0.01*SP1COVER))~
