Multilevel models with binary data
I have been using lme to model data with multiple nested random effects and
continuous response variables however I also have data with a binary
response variable, binomial errors and multiple levels of nesting of random
effects (e.g. site/block/quadrat/year), is there a package available which
will do this? Jim Lindsey's package "repeated" appears to be only able to
cope with 2

RODBC on Mac OSX pointers?
Hi,
I'm trying to get to grips with accessing my postgresql tables in R
using RODBC. I have Mac OS 10.2.8 (Darwin 6.8) installed and R 1.8.0
installed from source and I have updated RODBC to 1.0-4.
On the ODBC manager end, I am using OpenLink software's iODBC
Administrator and I've set up a User DSN called "PostGRES" - odbctest

Compile R-1.7.0 on Mac OS 10.2.6
Hi,
I can't get R-1.7.0 to compile on my Mac. Can someone give me some
pointers?
The machine is an 800MHz iBook running OS 10.2.6. I have installed the
December 2002 Developers Tools and have installed g77, f2c and dlcompat
via fink. I've checked the versions of g77 and gcc and they're both
based on gcc version 3.1. I've got Apple's X11 (Beta 3). I've added

matrix for diversity functions?
Hi,
I have a small simple data frame (attached) - to compare diversity of
insects encountered in disturbed and unditurbed site. What i have is
the count of insects - the total number of times they were encountered
over 30 monitoring slots.
Can someone please check for me to make sure how the 'community data
matrix' for the diversity function needs to be oriented so that i'm

Matrix problem - possibly use of 'outer'
Hi,
I can't get my head around this - can someone give me a pointer:
I have a vector of values ('orig') representing areas and I want to
calculate the amount contributed by each original vector values in a
new vector ('new'). I find this hard to explain so here is a graphical
explanation:

orig <- 10:1 #10 values with varying area

zero variance in part of a glm (PR#11355)
In this real example (below), all four of the replicates in one
treatment combination had zero failures, and this produced a very high
standard error in the summary.lm.

Just adding one failure to one of the replicates produced a well-behaved
standard error.

I don't know if this is a bug, but it is certainly hard for users to

plotting multiple animal tracks against Date/Time
Dear list,
I would like to create a time series plot in which the paths of several individuals are stacked above each other, with the x-axis being the total observation period of three years ( 1.1.2004 to 31.12.2007) and the y-axis being some defined range[min,max].
My data consist of Date/Time information and the paths of 45 individual as the distance from the location of release. An example

Why doesn't outer work?
Hello
I'm a population ecologist and use R for all my stats and modelling.
Recently I have been using R to numerically solve integral projection
models. This involves constructing several large matrices. The current code
by Easterling (Size-specific sensitivity: Applying a new structured
population model. Ecology, 2000, 81, 694-708) uses nested loops to construct
the matrices. To speed up the

Ca't run R on NT4
I'm using NT 4, service pack 3, and running rjune.exe, dated 23/9/98.
This works fine when I'm logged in as administrator, but when a user logs
in, R fails with the message 'memory problem'.
I assume that R needs (write?) access to something to which our user
accounts don't normally have access. I tried giving the account full access
