block statistics with POSIX classes
...ion aggregate, but how to define the 'by' argument with POSIX variables?
Thanks!

gibbs sampling for mixture of normals
hi
i'm looking for a gibbs sampling algorithm for R for the case of mixture of K
normals, and in particular for the case of bivariate normals.
i'd be grateful if anyone could send its own R-routine, at least for the
univariate case.
thank you in advance

Bessel function
Dear all
Currently, I'm implementing the generalized hyperbolic distribution into
Splus. Unfortunately the Bessel function is not implemented in Splus. In
R the Bessel function does exist but it is an internal function and I'm
not able to look at the code.
Is there any possibility to see the code of the Bessel function in R or
does anybody has an implementation of the Bessel function in

linear constraint optim with bounds/reparametrization
Hello All,
I would like to optimize a (log-)likelihood function subject to a number of
linear constraints between parameters. These constraints are equality
constraints of the form A%*%theta=c, ie (1,1) %*% 0.8,0.2)^t = 1 meaning
that these parameters should sum to one. Moreover, there are bounds on the
individual parameters, in most cases that I am considering parameters are
bound between zero

Giving a first good impression of R to Social Scientists
Dear all,
in the coming Winter Semester, I will be a teaching assistant for a course
in Survival Analysis. My job will be to do the lab sessions. The software
used for these lab sessions will be R. Most of the students have a
background in social sciences and the only stats package they used so far is
most likely SPSS.
So I assume they might be quite surprised the first time they see R
