is there any package that allows for a division of two polynomials?

\mathcal symbols in R?
Hello,
Some time ago, I discovered the possibility of using mathematical
symbols for axis labels etc. In order ensure consistency between text
and graphics of some paper, I would like to include the calligraphic H
(obtained in LaTeX via \mathcal{H}) in several diagrams. Is there any
way to do so? Is it in general possible to use further mathematical
fonts like \mathbb and \mathbf in R?
Best

R OS X
Hi,
with newest R.app (1.11) / R2.1.0a
if a package is installed for the current user, it is not installed
properly (does not get an installed version entry and is not
loadable). If installed system wide it works.
The package I installed is xgobi.

Wishlist - better object.size() function
Some time ago I came across the function object.size() to estimate the
size of an R object. I don't know if the behavior of the function is
intended to be quite "user unfriendly" as it is right now or if just
nobody was thinking/caring about it.
I have two suggestions to improve it:
- Why is it named object.size() and not just size()? The latter would be
far more intuitive and

apply function
Hi all,
I have a question about apply function. Is that possible to pass some
non-default arguments in the function we want to apply ?
For example:
if "mat" is a matrix and I want to use the "tabulate" function on its row.
The command apply(mat,1,tabulate) works but I have problem with this one
apply(mat, 1, tabulate(nbins=4)).
Any clue ?
Thanks,
Eric

mboost: Interpreting coefficients from glmboost if center=TRUE
Sorry for the tardy reply but I just found your posting incidentally
today. To make long things short:
You are right about the centering. We forgot to correct the intercept if
center = TRUE. We lately found the problem ourself and fixed it in the
current version (mboost 2.0-3). However the problem only occurred if you
extracted the coefficients. As the intercept is rarely interpretable we

[PATCH/DRAFT] Embed metadata into object file
Hi,
so this is my first contribution to LLVM/clang, so I hope I come close
to the required coding standards and guidelines.
First, I will describe the scenario I want to solve: For a few days, the
clang plugin interface allows to execute the a plugin just before the
actual main action (e.g., compiling an translation unit). In my case,
the plugin we're developing will analyze the AST and

BUG: ssh hangs on full stdout-file-system
System: Linux 2.4.18, openssh-3.4p1
Problem:
I use "ssh" and "tar" to backup remote directory trees to a local
hard-disk/file-system:
# ssh remote.server.org "tar -cz /home" >/backup/remote.tar.gz
If the backup-file-system runs out of space before the backup
completes, ssh starts hanging (waiting for the stdout-write to
complete).

multcomp and lme (followup)
I just realized that in the call to `csimint' the argument `asympt=TRUE'
is missing since we need to compute the confidence intervals for a glm
based on the normal approximation.
