Hi all,
I am wondering how to write a 'list' object to a file. I already gone
through some threads like
http://mail.python.org/pipermail/python-list/2001-April/080639.html, however
could not trace out any reliable solution. I tried following :
> write.table(calc, file="c:/data.csv")
Error in data
k-means uses Euclidean distance, so scaling of the variables does matter.
Whether you want to standardize depends on the example (as it does in most
multivariate analysis problems, e.g. PCA has the same issues).

Simple question re k-means. If I have a data set with columns that are on

should we first standardize the columns of the dataset so that each co

You seem to be confusing several issues.
First, being object oriented does not mean that it matches C++ syntax or
that every object is guarenteed to have specific methods. What lead you
to think that a recordedplot would have a metafile method? Nothing else
has that method, and the only function
plot(0, 0, pch=21, bg="#FF22", col="#FF01")
may be (close to) what you are looking for.

dear all,
IÂ have a problem about "spline", when I send this:
library(mgcv)
attach(SG2)
modele3 <- gam(J15STATUS~SWANG1+s(AGE)+ s (SP2),data=SG2,family=binomial)
it doesen't work et it says:
Erreur dans get(".Random.seed",envir=.GlobalEnv)
variable".Random.seed" introuvable
Thanks a lot

try this:
mat <- sample(0:1, 49, TRUE)
dim(mat) <- c(7, 7)
mat[c(1,4), ] <- 0
ind <- rowSums(mat == 0) != ncol(mat)
mat[ind, ]
I hope it helps.

Hi Stephan,

You can cache the results for reuse in the gradient call (most easily by
sharing an environment between them).
I don't think nlmin exists in R (nlm does), but doing it that way wastes
gradient computations where they would not be used. Your usage may be
exceptional, but for most usages the gra
Dear all,
I want to model presence/absence data of tree occurrence using a number of
predictor variables.
Absences of some sample points are probably wrongly specified (they should
be presences) due to land use which can not be incorporated as a predictor
because of some sort of arbitrariness. So

Dear Markus!
Since I did not see an answer yet, my suggestion is to use coxph with
the groups variable numerically coded as the only independent variable.

Ouch. Thank you Uwe! You are right, there are two R packages: rbugs and

Dear R-community,
I have matrices/tables of different sizes which may contain rows with
only zeros. Now I would like to delete these zero lines or create new
matrices composed only of the non-zero lines. Columns only containing
zeros I want to preserve.
Here an example:

Dear all,
I am using the functions 'optim' and 'nlminb'. For both, you can provide
a function which computes the gradient of the objective function (to
enhance speed and precision). In my case, both the objective function
and the gradient take time to be computed and share many common
