Hi I'm hoping someone can help me I am a relative newbie to R. I have data that is in a similar format to this... Experiment Score1 Score2 X -0.85 -0.02 X -1.21 -0.02 X 1.05 0.09 Y -1.12 -0.07 Y -0.27 -0.07 Y -0.93 -0.08 Z 1.1 -0.03 Z 2.4 0.09 Z -1.0 0.09 Now I can easily have a look at the overall correlation of score 1 and 2 by doing this plot(data[,2], data[,3]) or fit <-

I was hoping that AR''s find_by_* magic methods would help me retrieve multiple items somewhat like the following: names_to_find = [''Larry'', ''Moe'', ''Curly''] found_people = Person.find_by_name(names_to_find) Is there a way to accomplish this using find_by_* (or even find(:all) using some sort of conditions) or must I resort to SQL

Has anyone implemented a t-test with the effective sample size correction proposed by Dale and Fortin, Ecoscience 9(2):162-167, 2002, using a discussion by Cressie, 1993, page 15? thanks, Denis

I have a theory on the cause of a problem but it is still only a theory. I wonder if anyone here can confirm. I have a multi-isp configuration with a multi-path default route to each ISP, equally weighted. I am seeing, periodically, traffic dropped due to martian detection and errors logged on inbound traffic, but at other times, that same exact traffic will be allowed, no errors. My

Hello. I am trying to make use of rsync for backup purposes. I want to use it with the -b switch: it renames older FILE to FILE~ instead of replacing it with the newer version. This way, only the newest and the second most recent versions of a file are saved. I want to have more versions. One approach to this can be inpired by --backup-dir operation. I'd rather extend the backup

Hi! I'm running Samba 1.9.18p7 on a machine with two interfaces, so I configured: ; multiple interfaces interfaces =x.y.z.7/255.255.0.0 a.b.c.d/255.255.0.0 ; paranoia setting: to be REALLY sure which host name samba uses as NETBIOS name netbios name = XYZ001 This one has to register with a WINS server on one of the nets, so I configured: ; be a WINS client wins

New to Asterisk's and loving it so far. Does anyone know of any functionality in Asterisk's (or more so phones) that allows line numbers to be lit up like a switch board on a phone? So that someone can page another person with 'call on line 3'. I'm not really a telco guy and are still learning terminology for things. Any idea's? -- Regards, JB Hewitt Business:

Hi Paul, thanks for your answers. > 3 DSL (ppp0,ppp1,ppp2) providers from the same ISP. (which means they have > the same gateway, but different static ISP''s) Do they actually have the same peer address? The connection is pppoe, the gateway is assigned by the ISP and the 3 ADSL connections next hop is to the same Router at the ISP. The gateway is the same for all 3 connections

Hi, I'm in the process of adding support for Markdown to a minimal CMS in Rails, [Railfrog][railfrog], which uses mime types to select appropriate processing. I have had a look through the archives but have not been able to see that a consensus has emerged as to what such a mime type for Markdown should look like. My reading of the RFCs suggests that it should be within the "text/*"

Hello all, I've began writing the parsing section of the spec, and I though I'd let you know about where I'm heading with all this. Basically, parsing is defined as three consecutive passes: parsing document elements, parsing block elements and parsing span elements. Each pass is going to contain a set of rules the parser should attempt to match while parsing the input. Rules

There are now several R geographic user groups, and a few have mailing lists on the R mailing list system. Thanks to Martin M, there's also a pointer to a page I'm maintaining to list/describe the groups. The page is at http://macnash.telfer.uottawa.ca/RUG.html Contact me if you have a listing. I'm prepared to wikify it if there is sufficient interest. John Nash

google for "centos error performing checksum" refers to createrepo but of course "yum install createrepo" also fails and the instructions appear to be overkill.

Hi, I''ve noticed that defining multiple facts in one file is possible, and puppet can make use of them correctly, but when trying to call with facter --puppet they are not shown, do I need something special to make them work as any other single custom fact? Master is running 2.6.7 This is a custom fact with two facts in it: [modules/foobar/lib/facter/foobar.rb ] require

This update to PHP Markdown fix a bug that slipped in the WordPress interface with the last update. It also introduce a new "feature": you can now instruct the parser to ignore HTML tags and/or entities in the input. You can do this by instantiating yourself the parser and setting the `no_markup` or `no_entities` properties to true: $parser = new Markdown_Parser;

Ravi Varadhan and I have been looking at UCMINF to try to identify why it gives occasional (but not reproducible) errors, seemingly on Windows only. There is some suspicion that its use of DBLEPR for finessing the Fortran WRITE() statements may be to blame. While I can find DBLEPR in Venables and Ripley, it doesn't get much mention after about 2000 in the archives, though it is in the R FAQ
