How to formulate quadratic function with interaction terms for the PLS fitting model?
I have two ideas about it. 1- i) Entering variables in quadratic form is done with the command I (variable ^ 2) - plsr (octane ~ NIR + I (nir ^ 2), ncomp = 10, data = gasTrain, validation = "LOO" You could also use a new variable NIR_sq <- (NIR) ^ 2 ii) To insert a square variable, use syntax I (x ^ 2) - it is very important to insert I before the parentheses. iii) If you want to make the interaction between x and x ^ 2 use the command ":" -> x: I(x ^ 2) iv) For mul...

large files
I'm reposting this problem (perhaps a bug) now I've got more information on it. This is another point of view of the situation and I hope someone could have run into the same trouble before (and solved it :-)) This is it: * with ntbackup 2000 I create a 22Gb .bkf file in the windows machine. * I can copy that file over a samba share and get correct info form the file in windows

OT: Good soft-phone on Linux
Hi Folks, I am wanting advise on a good soft-phone on Linux. I have looked at Gnophone but cannot seem to get it to compile under debian sarge. I am now looing at sipXphone seem to be picking up that it is not that stable, but perhaps someone here can advise on what softphone I can use on Linux.

Re: gcc 2.95.2/irix/Laguerre_With_Deflation/inifinte loo
Sorry about the one-man thread but if someone would slap me... floor0_forward is declared "int". It returns "val". "val" is declared "long". "val" is assigned the return from "rint" which is "double". Am I misreading this? ber --- >8 ---- List archives: http://www.xiph.org/archi...

Compile Rd file
Hello, I am trying to compile a file .Rd into .html using R CMD Rdconv -t=html /file.rd/>/file.html./ It seems that the process works ok but instead of having for example loo.cv(NMRTools) at the top of the html file I have loo.cv{unknown}.

Leave One Out Cross Validation
Hi All, I have been trying to get this LOO-Cross Validation method to work on R for the past 3 weeks but have had no luck. I am hoping someone would kindly help me. Essentially I want to code the LOO-Cross Validation for the 'Local Constant' and 'Local Linear' constant estimators. I want to find optimal h, bandwidth. Than...

unexpected.tdb
I have been using samba 2.2.2 for quit awhile running with security= share in my company. I looked into the /var/lock/samba and found a growing file unexpected.tdb. Is there a way to trim it down while samba is running or do I have to start and stop samba? Is this an expected behavior? TIA Joseph Loo

...unction with interaction terms. But I am not sure how. I will use an example to illustrate my problem: Following the example in the PLS manual: ## Read data data(gasoline) gasTrain <- gasoline[1:50,] ## Perform PLS gas1 <- plsr(octane ~ NIR, ncomp = 10, data = gasTrain, validation = "LOO") where octane ~ NIR is the model that this example is fitting with. NIR is a collective of variables, i.e. NIR spectra consists of 401 diffuse reflectance measurements from 900 to 1700 nm. Instead of fitting with predict.octane[i] = a[0] * NIR[0,i] + a[1] * NIR[1,i] + ... I want to fit the...

Fw: Help with PLSR
...... I am now stuck while conducting the plsr. I have tried various methods of creating structured lists etc and have got nowhere. I have also tried many incarnations of BHPLS1 <- plsr(GroupingList ~ PCIList, ncomp = FeaturePresenceExpected[1], data = FullDataListTrans, validation = "LOO") Where am I going wrong. Also what is the easiest method to identify which of the 94,000 peptides are most important to the variance between groups.

I'm running RH7.1 and Samba 2.2.2 . I would like to offer a VFAT partition on the server hard drive for universal read-write access. I mount the partition in fstab with /dev.hda5 /sys vfat defaults,rw,uid=1001,gid=1001 0 0 It mounts fine and shows up on the Windows 98 machine and can be opened. I can't write to it however.
