And what does this have to do with the lead thread subject line "Transition
Matrices"?
I guess the only way we can start enforcing thread discipline is to stop
responding to threads that hijack others?
Any thoughts?

I wonder if there is any tutorial explaining, step by step, how to convert a
(georeferenced) map boundary (from esri shape-file) into a Spatstat window,
for performing the analysis of marked point patterns surveyed inside that
map. Any help on the subject will be really appreciated.

Have you considered the "sem" package (for "structural equation
modeling"), which (to me at least) is a generalizion of MANOVA with
canonical analysis. Alternatively, have you considered partial least
squares (e.g., packages "pls" or "plsgenomics")? I haven't used them,
but they sou
Hello everybody !
I try to obtain in R eigenvectors and canonical analysis on MANOVA results,
but I don't find how to process?
In particular, I would be interesting to obtain "standardized canonical
coefficients" of the canonical variates. There analysis give some

Another possibility is eapply where I have used naCount
from Henrik's solution:
prop <- function(x)
list(class = data.class(x), dim = dim(x), size = object.size(x), NAs
= naCount(x))
do.call("rbind", eapply(.GlobalEnv, prop))

hi, i got just one question concerning R-Project. How can we simply

I am having difficulty obtaining the scores from my principal component

data set that I am using this time is similar to what I have used in the

Sorry
I'm student in biomedical engineer and i have to solve this formula
for immuno-assay. I need to design a calibration curve
But i don't understand How can i write this formula in R language:
y = a + (c - a) /(1+ e[-b(x-m])
where
x = ln(analyte dose + 1)
y = the optical absorbance data
a = t

I assume you mean the following:
chemYield <-
function(a, x)(a[1]+(a[3]-a[2])/(1+exp(-a[2]*(x-a[4]))
If you want to estimate parameters a[1:4] from data on pairs of (x,
y=chemYield), create a data.frame(x, y), and estimate the parameter
vector "a" using "nls".
If you have trouble getting
