Sending E-Mail from R
Hi, Has anyone used R to send out an email via an SMTP server? I run R from a script and would like to be able to send out an email from there also. I could shell out to an email program, but was hoping maybe someone had a package for R or a smooth way to do it. Thanks, Josh [[alternative HTML version deleted]]

Stock Price Correlation to Index Price Levels
Hi, This is probably trivial to most people out there, but I'm struggling with this. I have a data set which contains the closing prices (properly adjusted for dividends and splits) for several hundred securities and the closing prices for a general stock market index (S&P 500). I have no problem getting it into R with RODBC and manipulating it. There are no missing values. I can

2.2.2 runaway SMBD process
Hello, I am running Samba 2.2.2 with acl-0.7.16 on RedHat 6.2 (2.2.19). The PDC is a Windows 2000 Server and the Samba server is a domain member using Winbind. All the workstations are Windoze 2000 Pro with SP2. Everything seemingly works fine but every day or two I get a runaway SMBD process which hogs the CPU and becomes unkillable. The only resolution is to reboot the server completely.

Cisco 7970 problems
Has anyone had problems with a Cisco 7970 running sip image SIP70.8.0-2SR1S hanging up zap channels? Calls to SIP and IAX are fine. Just when the call goes out via the zap channels I have some Cisco 7960 running SIP and they work fine. Any ideas?

I dont know gentoo, but the package might be called iproute2. You might also need the bridge-utils. Regards Dominik Friedrich Nietzsche schrieb: > Thanks found the issue atleast, here is what I get: > > xentest scripts # which ip > which: no ip in >

Valid Users in Samba 3
All - I'm having a problem with the "valid users" directive working. I have an Accounting share that only the Accounting department should have access to. However, I am unable to lock the directory down so only they can access it. I am running samba-3.0.0-2 from an RPM on RedHat 9.0. Below are details of my trials. This is a pretty urgent need, please. Thank you! smb.conf

[LLVMdev] -fomit-frame-pointer on intel darwin
Can anyone shed some light on the origins of the comments... /* Mach-O doesn't support omitting the frame pointer for now. */ ...in gcc/config/i386/i386.c. FSF gcc trunk has enabled the omit-frame-pointer option as the default for both i386 and x86_64 recently. * config.gcc: Handle --enable-frame-pointer. * configure.ac: Add --enable-frame-pointer. * configure: Regenerated. *

How to truly separate Logic from view with Rails?
It is something that I have been wondering. When working with other application servers there is often/most of the time a 3 tiers/layers architecture: - Presentation layer/Web services - Application layer - Database layer They often resides on separate machines, 3 different sets. So the application code is logically AND physically separated from the presentation layer. Is this possible with

Width of text displayed in R
All, I think this is pretty basic but I couldn't find the answer in any source. I have just built my own R for Linux (amd 64). It runs well, but R thinks that it only has 80 characters or so of screen width. I log on with Putty to the box and can stretch it as large as I want. Is there a simple way to tell R to use more screen width when displaying? From whatami: OS RELEASE :

really irregular time series
I built some reasonably successful tools in a graphical database for reconstructing the developmental turning points for feedback loop driven natural processes. I'm trying to move it to R and am having difficulty with the very basics, i.e. a) defining time series using time as a natural number rather than a place in a table. I was also hoping b) someone might have built some of the

how long before deleting sessions ?
What is the recommended amount of time to keep sessions around in the database (i store them in a sessions table). IF you get 1 million requests per day you are going to get 1 million new session entries in the DB. This would need some serious cleaning so just wondering what a safe cleanup time would be. Also does anyone know how to prevent new sessions records from being created if session

wbinfo -r 'username' displays inconsistent results across DC's
Hello,     Looking up a users group membership I'm showing different results on each DC. UID and GID mapping appears consistent but not all group membership is displayed. I've verified idmap.ldb is backup up and copied over to the other DC's. I do notice when taking a hot backup of idmap.ldb, the file size is dramatically smaller than the original.
