EMACS/ESS problems
Hello all,
since we're on the topic of R-editors. I am using emacs/ess on a unix
workstation (to interact with R and have been having a little problem. I
usually write the R commands I need to run in a separate buffer then
copy and paste them into the *R* buffer for evaluation. The problem is,
if any command is spread over multiple lines emacs/R hangs when I paste
it in the R buffer for

silhoutte.default bugs
Hello all,
This might have been fixed in later versions (I am using R1.7.0), r-help
archive contains messages reporting similar problems but no reports of
codes fixes. I have encountered a couple of problems using the
silhouette function. one occurs when the clustering contains clusters
composed of 1 element (Martin Maechler posted code few months ago that
fixes a similar problem that occurs

debugging non-visible functions
Hi,
I would like to step-through a non-visible function. but apparently I

Non-visible functions are asterisked

model-based clustering
Hello,
I was wondering whether a Poisson mixture modeler/cluster analysis
package is available for R. I scanned CRAN packages and couldn't find
anything but I thought I'd ask. If not could anyone recommend a non-R
open source package. I have found 'snob' but this program seems a bit
hard to use in an automated, non interactive fashion.
regards,
Murad

help on barplot
Hello,
I am trying to compare two histograms using barplot. the idea is to plot
the histograms as pairs of columns side by side for each x value. I was
able to do it using barplot before but I can't remember now for the life
of me now how I did it in the past:

Multiple graph sheets
In Splus the code
test.lm <- lm(y ~ x, data = test.data)
plot(test.lm)
generates a graphics window that contains
multiple graph sheets that one may choose
from via the "page" tabs at the bottom of
the window.
Is there a way to do this sort of thing in
R? As another example, I have some repeated
measures data with continuous outcomes and

Problem Writeing a pipe using R (stdin is consumed)
Hi everybody,
I a, trying to use R as a pipe like this:
cat inputData | R --silent RCommandFile >outputData
The RCommandFile would contain something like readLines(stdin()).
I have tryed various things and none did work cleanly.
One possible solution is to use the pipe() function inside R and to pass in the "cat inputData" however this is not very convenient

Mongrel grammar file
Hey Zed, any chance you mind sharing the grammar file you use with
lemon to create the parser? I''ve been meaning to sit down and learn
how to use one of those things. If not, any suggestions on a good
resource for learning how to use a LALR parser?

Which libtiff 3.8.2 do I grab?
Via google: libtiff 3.8.2
http://rpm.pbone.net/index.php3/stat/4/idpl/2839214/com/libtiff-3.8.2-2.x86_64.rpm.html

for other distributions.
So which do I take?

Using Puppet's client certificates for Apache, SSLVerifyClient
Hi -
I read up on this subject quite a bit, and was able to find a few
posts on the mailing list, even found a wiki article. Unfortunately
it doesn''t quite address what I''m looking to do.
From what I understand, Puppet''s client/server authentication system -
using SSL - is portable. I believe that I should be able to use the
same SSL certificates and keys (and even

grid and gtkDevice package clipping bug.
Hello!
When I draw points on grid's viewport with clip set to TRUE clipping
does not have effect on some symbols. It happens only when drawing over
gtkDevice (GTK ver. 1.2) (with postscript device clipping works OK -

CentOS-6.5 rescue disk?
Is there such a thing as a CentOS rescue disk?
Google gives many links to such a thing,
but when I pursue them I do not get to an URL

Status of OL / OB flapping with no real pattern
Hi, all -
I've searched the archives, and although I've come close to finding a
few things that describe my problem, I haven't been able to nail it
down.
Basically I've got 8 TrippLite SU3000RTXR3U's (Couldn't it be a simple
model number, like "4UPS"? hah!), and when I tap in to them with nutc,
I see that the status flaps back and forth between OL and OB quite

Preforming an action/trigger after a user successfully authenticates
Hi -
I have searched the docs for v1.0 RC7, but cannot find what I'm looking for.
What I'm ultimately wanting to do is have Dovecot preform some action,
or a trigger, when the user is successfully authenticated. Even more
specifically, I'd like to run another SQL query to record a date/time
for last authenticated login.

Perl modules not working properly when installed via yum?
Hello, all -
I've been dealing with this problem for quite a while, and most of my
solutions have just been dirty hacks. I'd like to find an appropriate
solution.
I've installed perl modules in the past via yum. Sure, they get
installed - but none of my perl applications can find them. I know that
this is a long outstanding issue, because I have yet to find a real
solution.

grid - deleting and erasing grobs?
Hello!
Don't quite understand how can I delete grobs and simultaneously erase
graphic output they produce. I first change grob's "vp" field to null
(grid.edit(gr,vp=NULL)) to erase it and then call rm(gr) (as grobs are
external pointers I'm not shure what this method actually frees
allocated memory).
May be there is simpler method?
Does garbage collector have any effect
