I think I understand tapply but i still can't figure out how to do the following. I have a dataframe where some of the column names are the same and i want to make a new dataframe where columns that have the same name are averaged by row. so, if the data frame, DF, was AAA BBB CCC AAA DDD 1 0 7 11 13 2 0 8 12 14 3 0 6 0 15

Hi I'm experiencing a strange problem on my dovecot 2.0.21 setup. When i delete a folder "foo" it was correctly moved in the trash folder. If i try to delete from it the folder "foo" from the trash it gets renamed "foo1". If I try to dlete "foo1" it gets renamed foo11, and the operation could be continued figured out in an endless loop. This

Hi @ll, now i am able to login samba 3 beta pdc, have homes mapped with read and write permission on the home ( this troubled too ) now i tested funktions from usrmgr ( old nt prog for create user and groups ) i can create user on the fly, i can create groups on the fly i can delete groups on the fly add and delete users to groups but if i want to dlete users with delete user script =

I thought I'd share this with the list since it appears to provide a quick fix to some memory problems, and I haven't see it discussed in relation to R. To reallocate virtual memory from kernel-mode to user-mode in 32-bit Vista or Windows 7 one can use the increaseuserva boot option value. See http://msdn.microsoft.com/en-us/library/aa906211.aspx On my 4GB Vista machine, R is now able to

Hi: I have been using Dovecot for well over a year now and it has always worked with few problems. The mail setup is not simple... Postfix+MailScanner+ClamAV+Docvecot+MySql+postfix.admin... just to mention the major things. The system is CentOS 5.3 on VMware. The maildir is on an NFS share, index and control is local. About a month ago I thought I upgraded from 1.1.x to 1.2.x. by doing an

Dear All, A new task view "ChemPhys" on chemometrics and computational physics is available on CRAN (http://cran.r-project.org/web/views/ChemPhys.html). It describes packages and functions that are of use in modeling chemical/physical systems. Suggestions and comments regarding this task view are welcome. If you think a new category, package or function should be added, please mail.

Dear all, I was interested to get an idea on how the computational complexity is affected by different modes, assuming a fixed complexity setting. I saw in the documentation (Table 4 http://www.speex.org/docs/manual/speex-manual/node10.html) that going to higher data bit rate does not always increase the complexity (e.g. 11 kbps require 14 mflops while 15 kbps require 11 mflops). Is this
