Function to "lump" factors together?
Sorry about the odd terminology, but I suspect that my intent might be completely missed had I used "aggregate" or "classify" (each of which appears to have some rather special meanings in statistical analysis and modeling). I have some data about software builds; one of the characteristics of each is the name of the branch. A colleague has generated some fairly interesting

Suppress blanks/spaces in character
Hi all I'm have a character vector and would like to suppress the blanks if there are more than one after the other. Example: Character value is: "abc def ghi" The result should be: "abc def ghi" I know that it's possible to delete the leading blanks with the command "trim". But how can I delete blanks within a character? Thank you very much in

Arrange values on a timeline
I have a set of labels arranged along a timeframe in a. Each label has a timestamp and marks a state until the next label. The dataframe a contains 5 such timestamps and 5 associated labels. This means, on a continious scale between 1-100, there are 5 markers. E.g. 'abc' marks the timestampls between 10 and 19, 'def' marks the timestamps between 20 and 32, and so on. a <-

Very simple traffic shaping script for H.323
Hello - What I want to do seems very simple - I want to make sure any H.323 traffic gets processed before anything else entering or leaving this network. The network has a videoconferencing device on the LAN at 192.168.16.4. A Linux firewall NATs an external IP Address to this internal address and I have appropriate SNAT and DNAT rules that work. The NAT and connection tracking rules all work

?nchar ?strsplit
Hi, my data frame is x<-data.frame(ID=c("abc/def","abc/def/ghi","abc","mno/pqr/st/ab")) I want to split my column ID using "/" as the place to split. How can I do that without telling the code how many sub-columns. I could use nchar(gsub("[^/]","",x$ID)) to get how many "/" are in each row of the column, but could

Search for (any of) multiple terms slow
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, this may be an obvious logical problem I'm not aware of, which cannot be solved any more efficiently... but maybe it's just a bug or there is potential for optimisation in Dovecot (or Thunderbird?). When searching for multiple terms at once ("any of") with Thunderbird/Dovecot (using FTS Squat indexes), it takes much longer (not

[PATCH 0/7] Various fixes for Ceph drives and parsing libvirt XML.
Miscellaneous fixes to: - Handling of Ceph drives now works end-to-end (RHBZ#1026688). - In particular, you can now use rbd:/// URIs in guestfish (and they work). - Parse Ceph & NBD network drives from libvirt XML correctly, so that existing domains with Ceph/NBD drives can be added (eg. using guestfish -d option). - Add more testing of the above.

Shortcomings of Maildir++ layout
Hi, I am trying to deal with the problem, that under regular mbox format a path can lead to either a file or a directory, but not both, while under IMAP, a path is usually both, a message folder containing subfolders. I found dovecot's approach to this problem, the Maildir++ layout described under http://wiki2.dovecot.org/MboxChildFolders , and was astonished to see, what problems come with
