-----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.

-----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

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I would like to code a script which processess all possible combinations of matrix columns. The purpose of such operation is to automatically find best combination of factors (not those factors in mean of R, but explaining factors -- independent variables) received from lm(). The independent variables are present in columns of the matrix. I am not a

-----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

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I need to read in a dataframe stored in a cvs file. The problem is I don't know how to tell R the first column (in format like "7-Jan-80") is a vector of dates. Could you help me, please?

As a true R-Newbie, I thought I would respond to Zed Shaw's ideas. I think they're all good. I've put comments re the ones which would be critical for me >>>1) An R Cookbook section of the site where people can submit pieces >>>of interesting code that satisfies a need. This would be similar to the >>>Perl/Python/Java Cookbook texts that O'Reilly

-----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

-----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:

I'm having troubles using rsync to synchronize only files+directories specified in "include list". I'm using command rsync -avP --include-from=list --exclude="*" /from/ /to/ The "list" file contains 2 entries: /a/b/file1 /file2 Rsync doesn't transfer file1 until I add all the subdirectories tree. It means I have to adjust the list this way: /a/

Are there any examples of bvt scheduler parameters usage? If I understand it right, bvt provides me with option to scale domain''s CPU usage. Eg. I have 2 (non-zero) domains pinned to the same CPU. Can I assign eg. 30% of CPU time to domain 1 and 70% to domain 2? (I mean in peaks when both domains are not idle and require the CPU time) If yes, how should I build the "xm bvt"
