confirms this): when there is a missing marginal term in the formula, the
higher-order interaction should be coded by dummy variables, regardless of
type. Thus, the terms() function is only following the cited behavior 1/3rd
of the time.

Since F_j refers to both categorical and numeric variables, the behavior of
model.matrix is not consistent with the heuristic.

Factor here is used in the more general sense of the word, not referring to
the R type "factor." The behavior of R does not match the heuristic that
it's citing.

Hi all,
I was installing a package *RBGL* of bioconductor. However, I had some
issues while installing it. I asked the devel group of bioconductor and
they told me to consult this group. Here is my conversation with the
bioconductor group related to the problem
*Me->*
I was trying to install the

[1] 2
I'd expect the last call to addSome to be 4, not 2.
Thanks,
Tyler

Or, are there better ways to bundle extension-specific third party
dependencies? ;) I'd rather not have
my users have to install obscure libraries globally on their systems.

There is something fascinating about science. One gets such wholesale

R is thread-safe if the actual simulation is being computed
in separate, shared C code?
I'm running my current, sequential code, on a cluster that supports both
OpenMP and MPI, should I figure out how to use it.
Thanks for your patience,

ah, that's better. For an immediate fix I just changed .dll to .so, and
it appears to work perfectly. I will read through Writing R Extensions
to make sure I understand what I'm doing!
Thanks!
