similar to: compiling issues with Mandriva Linux 2007 Discovery

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")

I am attempting to create a formula using as.formula for a PLS analysis. I have used the code below successfully, but in a previous R version and with many fewer predictors. Any help getting all of these predictors into one formula would be greatly appreciated. TC.fmla <- as.formula(paste("TC ~ ", paste(vars, collapse= "+"))) As I mentioned, this code worked fine in a

I am attempting to run principal components analysis on a dataset of spectral reflectance (6 decimal places). I imported the data using read.table and there are both column and row headers. When I run princomp I receive the following error: Error in cov.wt(z) : 'x' must contain finite values only Where am I going wrong? Ross

All, I have been using a data set to build pls models for three different soil properties. Two of the three models run fine; however I receive the following error for the final model. > libs.IC.cal <- mvr(libs.IC.fmla, data = libsdata.cond.cal, ncomp=20,validation = "LOO", method = "oscorespls") Error in colMeans(x, n, prod(dn), na.rm) : 'x' must

All, Apparently the attachment did not make it through the list serve. I am having difficulty installing R-2.4.1 on Mandriva Linux 2007 Discovery. Thanks to the help of Doug Bates I got further along the path (Thanks Doug!!). I now cannot figure out which line of code needs modified in order for configure to complete. Please see below for the last several lines of output. checking whether

I am attempting to write a routine where I can run PAM (partition around mediods) on a dataset containing multiple soil cores and PCA spectral data from several depths per core. I want to run PAM on each individual core, so I need to group the data by core to run the analysis. Below is an example of my data structure: Lab.id PC1 PC2 PC3 MAT057.2.5 2.438454966 -1.011182986 -3.040881377

I am new to Linux (not to R) and recently installed Mandriva Spring 2007 on my partitioned hard drive. My next objective is to install R in the Linux environment, unfortunately Mandriva is not one of the Linux distributions available for download... Could someone please let me know which distribution I should use? Thanks. Jonathan --------------------------------- Boardwalk for $500?

I was finally able to get R to 'configure', 'make', and 'install' on Mandriva 2007. Itried to install gnomeGUI and I received an error. See below. At what step do I make R a shared library?

Hi, I am studying using SVM functions of e1071 package to do prediction, and I found during the training data are "factor" type, then svm.predict() can predict data directly by categories; but if response variables are "numerical", the predicted value from svm will be continuous quantitative numbers, then how can I connect these quantitative numbers to categories? (for

Hi, I tried to add a progress bar to my script, but it seems the "txtProgressBar" function will wipe out what I want to print before it(for example - the "Hello" in following script), and the parameters "title" and "label" do not work either. How can I put a title for the progress bar? or is there any other better function I can use? testit <-

Hi, I am trying to read in my Affymetrix CEL files (48 files, total ~600 MB) but I keep getting memory errors. Can somebody please help me with this. Or is therea remote server I can send my data to for computation? Any help is much appreciated.

Hello, I 'm sure there must a be a simple explanation for what I'm doing wrong but I am stumped. I am a novice R user and this has shaken my confidence in what I'm doing! I am trying to run a simple ANCOVA using the model y~A*x, where y and x are continuous and A has two levels. Everything seems fine until I compare the output with what I get from another statistical package

1. You have levels(A) as "2" and "4", yet you showed equations for A=0 and A=1? 2. y = A + X + A*X means you're allowing the different groups of A to have different slopes. Probably not what you intended. 3. It's probably best to provide a small sample of the data (and R code) so we know how you got what you got. Andy From: Ben Ridenhour > > Hello, >

Hello, I am new to using R and I am having problems get boot() to work properly. Here is what I am trying to do: I have statistic called "cs". cs takes a data matrix (154 x 5) and calculates 12 different scores for me. cs outputs the data as a vector (12 x 1). cs doesn't really use weights, per se, however I have included this as one of the 2 arguments cs can take. I try

I think I've looked over every post that has acl or sid or winbind in it. I don't think this has been discussed quite this way. The symptom is similar to other posts but the environment is a bit different. We can do perms through samba, and we can see acls that have been set using setfacl, but we can't change the acls (e.g., add a user). We get: [2002/11/15 17:02:17, 0]

We have what may be a very, very bad situation here and I'm hoping someone may be able to point out either where I'm misinterpreting this or where I missed the memo. We're testing 3.0.23d so we can upgrade from 3.0.14a. Our servers are all currently Solaris 9, and we build samba from source with MIT krb5 and openldap libraries. We have used security = ads since 3.0 after having

Hi there, I am looking to install R on Mandriva-linux. But on the UK mirror site I found only Debian, Redhat, Suse, and Ubuntu, but not Mandriva. Any help would be greatly appreciated Thanks -- ------------------------------------ Abdel Hannachi Reading, UK

We've just built a RHEL 5 ES server to test the issues we've been having with group permissions since 3.0.23 (re: 3.0.23d UNIX vs. AD group permissions) and we found we have the same issue with the Redhat built rpm of version 3.0.23c. The following is the ldap and winbind portion of our smb.conf, the same as used on our current Solaris production servers: # ldap settings ldap
