I want to also store the legal values for many of those attribute fields in another database table. The problem is that 1) the sub-set of attributes

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 <-

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".

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

Request for added functionality - tracking and blocking attacks
Somebody please forward this, if this is not an appropiate place to ask the OpenSSH developers for a new feature. As many of us have seen, any sshd left open on the internet eventually becomes the target of password guessing attacks. I am aware of tools for scanning the security logs, and manipulating iptables to block ongoing attacks, but I am not aware of a way to configure sshd itself to

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
