Segmentation fault while using Mclust function of mclust library in R-2.0.1
Hi, all;
I got an unusual error while using mclust library 2.1-7 on R 2.0.1.
When I tried to run Mclust(rnorm(100)), I got segmentation fault error.
Does anyone know what causes this problem?
I came across the same problem even when I tried to run the example shown in
Mclust help using iris data.
Thanks in advance,

Special paper for postscript
Hi, All;
When I generate a "special" paper postscript image larger than "a4" or
"letter" using R, I can only see one-page portion of all image, of course.
What will be the simple solution for this? Is there any way I can set the
bounding box information on the image? Or any other suggestions?
Thanks in advance;

set class attribute method question
Hi, All;
Suppose I have a class 'dat' such that setClass('dat', representation
(.version='character', x='numeric', y='numeric')).
If I want to make a method that changes the .version slot of 'dat'
class in a way like set.version(d) <- '0.2' when d is an object of
'dat' class, how can I do this? Thanks in advance.

Way to make R idle for some time and try something again later
Hi, All;
I have a question. In R, what is the best way to make R idle for a while and
try something again later? For example, suppose there is an R job which
accesses a file that may be shared with other active jobs. So when the file
is being accessed by other job, your job will not be able to access the file
and your job will crash because of that. To avoid this, you want your job to
try to

Basically, the `Detail' section of ?tune says it all:

ESS does not recognize installed libraries
Hi, all. Something strange happened to my ESS.
I use Mac OS X. When R is used in stand alone mode, it recognizes
external libraries like "affy", "e1071" etc.
However, when R is invoked through ESS in Emacs, it produces errors
like:
Error in library(affy) : There is no package called 'affy'
Interestingly, I remember I successfully used these libraries through
ESS in

Web-application using R
Hi, all;
Our group is planning to develop a web-based analysis package with R. I
have some questions.
(1) Can we use R as a daemon-like way such that, after invoking R and
making it run in a kind of background mode, just put some R script into
R using some pipe-like mechanism and retrieve the result out of it?
(2) If this is possible, then how can we do it? If this is not
possible, then what

Library mclust in 64bit compiled R
Hi, All;
I tried to use library mclust in 64-bit compiled R 2.0.1 but failed.
Installation went smoothly without any warning or error. However, when I
tried to use them with the following simple code, it crashed.
Library(mclust)
Dat <- c(rnorm(20, mean=0, sd=0.2), rnorm(30, mean=1, sd=0.2))
Ind <- Mclust(dat, 1, 5)$classification

Absolute ceiling on R's memory usage = 4 gigabytes?
Hello. By way of background, I am running out of memory when attempting to normalize the data from 160 affymetrix microarrays using justRMA (from the affy package). This is despite making 6 gigabytes of swap space available on our sgi irix machine (which has 2 gigabytes of ram). I have seen in various discussions statements such as "you will need at least 6 gigabytes of memory to normalize

Memory problem ... Again
Happy new year to all;
A few days ago, I posted similar problem. At that time, I found out that our
R program had been 32-bit compiled, not 64-bit compiled. So the R program
has been re-installed in 64-bit and run the same job, reading in 150
Affymetrix U133A v2 CEL files and perform dChip processing. However, the
memory problem happened again. Since the amount of physical memory is 64GB,

Configuration of memory usage
Hi, all;
I know there has been a lot of discussions on memory usage in R.
However, I have some odd situation here. Basically, I have a rare
opportunity to run R in a system with 64GB memory without any limit on
memory usage for any person or process. However, I encountered the memory
problem error message like this:
Error: cannot allocate vector of size 594075 Kb

How does Asterisk scale to 500-1000 phones?
Anyone have opinions on how well Asterisk scales to 500-1000 stations, in
regards to reliability, system performance, as well as ease of management?
Assume relatively low call volume; let's say two public network PRIs (47
DS0s).

TAE to RJ11 connector (hope not OT)
Hi,
I'm trying to use a Detewe TA 33-clip but there is no rj11 connector on
it...only a TAE connector.
I'd like to create an adapter so I need to know which TAE pins to
connect to RJ 11 pins.
Is there anybody who knows where I can find a schema of that adapter?
Single connector pinout may help too.
TIA

Benchmark
Hello:
I modified benchmark used in
http://www.informatik.uni-frankfurt.de/~stst/benchspl.txt now the attached
code will work with R, except for last test for some reason (Sorry ran out
of time to play with this).
Immediate problem is that R does not show fraction of seconds. So, that
kinda makes comparison some what hard. I also looked at memory and CPU usage
on NT console. R seems to go

Connect to Visual? and Bench Mark
Hi,
Is there any possible way to connect to VB, VC++, Delphi, Python, etc...
to R?
I am trying to put some nice GUI using something like VB and use R as a
back end for computations. I search through the FAQ and help archive, but
could not find any.
I am willing to look at any tools on Sun/Solaris environment as well (Like
C or Python or Perl).
If anyone can share some examples, pls let me
