...IN 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.

...e 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?

...turns x1 x2 x3; x1 x2; x2 x3 and x1 x3. Which format should be the returned result? A vector? I will need to use it way like: matrix[, c(1, 2, 3)] for a returned set x1 x2 x3. I am almost sure all I am looking for has someone already done. I will appreciate any help.

...ED 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. The period is non-regular (it is not strictly daily nor working-days-daily).

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

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"
