Hi I am analysing a dataset of 40 samples each with 90,000 intensity measures for various peptides. I am trying to identify the Biomarkers (i.e. most significant peptides). I beleive that PLS with jack knifing, or alternativeley CMV(cross-model-validation) are multivariateThe 40 samples belong to four different groups. I have managed to conduct the plsr using the commands: BHPLS1 <-

While doing pls I found the following problem > BHPLS1 <- plsr(GroupingList ~ PCIList, ncomp = 10, data = PLSdata, jackknife = >FALSE, validation = "LOO") when not enabling jackknife the command works fine, but when trying to enable jackknife i get the following error. >BHPLS1 <- plsr(GroupingList ~ PCIList, ncomp = 10, data = PLSdata, jackknife = >TRUE,

All, I am working with NIR spectral data and it was great to find that the example in ?plsr also used spectral data. Unfortunately, I am having difficulty figuring out how the "yarn" dataset is structured to allow for the plsr model to read: library(pls) data(yard) yarn.oscorespls <- mvr(density ~ NIR, 6, data = yarn, validation = "CV", method = "oscorespls")

Hi, When I try a net logon from Windows 7 64-bit Business (don't have any other Windows machines), I get "The trust relationship between this workstation and the primary domain failed". The discussion I've found around the Web regarding this error message seems to be only in the context of the 30 day password expiry issue, where the solution is to simply rejoin the domain.

Hello, I have recently downloaded Sorcerer GNU Linux (http://sorcerer.wox.org/) which uses ISOLINUX for booting the installation CD-ROM. Problem is, I can not get the CD-ROM to boot. I have tested it on another computer, and it works fine (The CD-ROM has been written correctly). When I boot it on my home system, it gives me this error message: ISOLINUX 1.66 2002-01-01 isolinux: Disk error 00,

Ferm has_many :kinetics, Kinetic belongs_to :ferm. Kinetic has the fields ferm_id, brix and temp. In my ferms/index view I have a table listing the attributes of each ferm instance. I would like to display the most recent

Hello, Has anybody successfully called the Rmath library from C using the MS Visual Studio compiler (I am using Visual Studio 6.0)? I have compiled the Rmath library using gcc, and the 'test.c' program (which makes a call to qnorm) works fine when compiled with gcc. However, I get a fatal memory error when I run it after compiling it with Visual C. Would this memory problem be related

Hi, I have experimental response (Y) and many (important or not) actions (X). I want to create model: Y = aX1 + bX2 + ... + eX5 (1) from few most important actions of course. As I understand I have to use plsr for this task. I learned read.table and plsr R functions and how to plot some results from them, but still do not understand how I can get (or construct) function I need (function 1)?

Hello, I have a data set with 15 variables (first one is the response) and 1200 observations. Now I use pls package to do the plsr as below. trainSet = as.data.frame(scale(trainSet, center = T, scale = T)) trainSet.plsr = mvr(formula, ncomp = 14, data = trainSet, method = "kernelpls", model = TRUE, x = TRUE, y = TRUE) from the model, I wish to know the

Dear readers, can anyone give an example how to use cross-validation in the plsr package. I miss to find the number of factors proposed by cross-validation as optimum.

Hi I am attempting to use plsr which is part of the pls package in r. I amconducting analysis on datasets to identify which proteins/peptides are responsible for the variance between sample groups (Biomarker Spoting) in a multivariate fashion. I have a dataset in R called "FullDataListTrans". as you can see below the structure of the data is 40 different rows representing a

Hi, With some help I learned how to use plsr(Y~x, 2, data=my) function in R (and build "my" from vector "Y" and matrix "x"). But still I have question about results interpretation. In the end I want to construct prediction function in form: Y=a1x1+a2x2 But I do not understand how to do it. Documentation do not describe this. Thanks for help. ;) [[alternative HTML

I am having a similar problem understanding the data structure of the "yarn" dataset described in the "[R] data structure for plsr" posts. I have spectroscopic data I'd like to run through a PLSR and have read the tutorial series, but still do not understand the data format required for the code to process my data. My current data structure consists of a .csv file read into
