Hi,
Thanks for answering so quickly.
Actually, I do not have the John Fox's book. On this webpage, there is a
handout for logistic regression (GLM I'm interested in) (cf.
http://socserv.socsci.mcmaster.ca/jfox/Courses/SPIDA/logistic-regression-handout.pdf).
The summary function return standard e
I get this with R 2.7.2 (and 2.7.1, and 2.6.2, but NOT 2.4.0):
> X11() # this one opens up okay
> X11("foo")
Error: Couldn't find per display information
$
and R crashes out back to my shell prompt.
If I do X11("foo") as a first command I get a meaningful error and my
R prompt back:

How can I define environments within a function so that they are visible
to calls to a sub-function?
I have defined an objective function,
ProfileErr = function(params,...)
which I would like to optimize using standard routines (optim,
nlminb,) but which contains auxiliary variables
This is an Xt error, whereas the first one is an Xlib error. It is easy
to trap it.
You do realize that this will never work? In the current setup all open
X11 devices must be on the same display, and 'display' is ignored if a
device is already open. (I don't know if that is documented: I d

I think you need to give a simplified, runnable example. (Or at least
runnable until it hits the scoping problem you've got.) "Sub-function"
isn't R terminology, and i

The code is:

Hi (Roger),
I saw the announcement of filehash v2.0 and the sentence "This
development has lead to better file locking for concurrent access and
faster reading and writing of data in general" caught my attention.
What kind of file locking do you refer to here?
I am looking for a mechanism that ca
