last day of month values
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I have a stock market trading values time series. What's the best way to extract the "last day of month" values. I looked at function window() but doesn't appear suitable for this since it expects regular dates.

covariance of equal date values
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I need to count the covariance of two time series. Both of them contain the dates' vector and vector of values. But the dates are not the same. It means some dates of first ts are not in the second respectively. And I need the covariance of same dates, of course. Could anyone help me, please? Thank you. lukas - -- Lukas Kubin lukas.kubin at

creating time series from existing data
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Is it possible to create a time series from existing data frame? One column of that frame contains dates (like "01/01/01") and the second one the values.

predicting financial time series
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 What are the best tools (models within R) for use in predicting stock market trading values? Currently I'm using the smooth.spline but are there any others used in practice? Do I find the mathematical formulations of R-functions somewhere (I now I could deduct it from the source code algorithms but ...)? Of the smooth.spline() for example? Thank

Rsync synchronizes unchanged files
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I wish to use rsync to synchronize a whole fat32 (MSWindows) partition mounted into a linux system. I run rsync from linux. The problem is rsync synchronizes most of the data even if the data hasn't changed since the original image was made. I used the -avz parameters to do the backup and the same for restoration. Also I've tried just -rvz. It

Character set of filename problem?
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I'm getting the rsync error "partial transfer (code 23) at main.c(925)" when restoring a 'rsync-ed' Windows partition from a Linux system. I feel the problem might be caused by the characterset (win-1250) which the files on Windows partition are stored in. Is there any solution to this? Thank you lukas - -- Lukas Kubin phone:

IMAP EXPUNGE disconnect/box hang - Fedora Core 2, Squirrelmail and Evolution
I'm a bit befuddled by this behavior. I've been using dovecot for close to a year, and recently the Fedora Core 2 Update: dovecot-0.99.13-4.FC2 build came in via yum. Since then I occasionally get this EXPUNGE disconnect error. When the error hits, the box does not crash but I can no longer log in*, nor start any new processes. I happen to have gkrellm running and I see a slow but steady

Question on randomization
Hi , I am using OpenSSH4.3p2. One of the fixes in this release says that random seed generation is not necessary for each key generation and initial seed will be served for the re-exec'ed processess. As better random seed will yield better random number generation, how can we achieve true randomization by one time random seed ? Thanks, Ponraj M

Greetings, I''m certainly :-) too thick, but after reading Ferret and AAF''s documentation I''m still wondering if I really need a DRb server in production. At the moment, the planned structure for production mode is a single server running the app with Apache and fastcgi; as far as I know, Ferret is multithread-safe, isn''t it? So, is a DRb server required to

MySQL typical set the default interactive_timeout to 8hrs (28800) this has bitten me a few times with sleeping processess

multiple daemons on the same port
I thought if a daemon is already running on the default port, I thought the additional ones started on the same port will result in an exit with error, but somehow it seems to work just fine. If I kill the first process, the second process seems to take control of the port. As far as I know you can't have two processes binding to the same port, so does that mean the second process is just
