Principle component analysis function
Dear All, In a package, I want to use PCA function. The structure I used follow this page: http://www.statmethods.net/advstats/factor.html. fit<-principle(mydata, nfactors=9, rotation=TRUE) or: result<-PCA(mydata) But I don't known why R language in my computer noticed: "not found principle", "not found PCA". I download and installed

Orthoblique rotation on eigenvectors (SAS VARCLUS)
Hi All, I'd like to build a package for the community that replicates the output produced by SAS "proc varclus". According to the SAS documentation, the first few steps are: 1. Find the first two principal components. 2. Perform an orthoblique rotation (quartimax rotation) on eigenvectors. 3. Assign each variable to the rotated component with which it has the higher squared

Latex errors (build on windows)
Where can I found hepl about latex errors: the R CMD check tells me less, but: * checking PDF version of manual ... WARNING LaTeX errors when creating PDF version. This typically indicates Rd problems. * checking PDF version of manual without hyperrefs or index ... ERROR Re-running with no redirection of stdout/stderr. Hmm ... looks like a package Error in texi2dvi(file = file, pdf = TRUE, clean

Principal component analysis with EQUAMAX rotation
Hello, I need to do a principal component analysis with EQUAMAX-rotation. Unfortunately the function principal() I use normally for PCA does not offer this rotation specification. I could find out that this might be possible somehow with the package GPArotation but until now I could not figure out how to use this in the principal component analysis. Maybe someone can give an example on how to do

ploting axes and rotating strings
Hello! I have two question that rose from trying to tacle the same problem in two differnet ways. What I want to do is to plot axes (only values or labels, no tick marks) in such a way that 'cex' can be very small, text can be perpendicular to the axis (as in axis(las=2) ) and the text is stil at the right position. Let me demonstrate with a small example:

varimax rotation difference between R and SPSS
Hi, I am puzzeled with a differing result of princomp in R and FACTOR in SPSS. Regarding the amount of explained Variance, the two results are the same. However, the loadings differ substantially, in the unrotated as well as in the rotated form. In both cases correlation matrices are analyzed. The sums of the squared components is one in both programs. Maybe there is an obvious reason, but I

Factor analysis in R
Hi all, is it possible to run factor analysis in R such that the routine returns - unstandardized factor scores (according to the original scale) - rotated factor scores (these may be standardized) So far I have only found the possibility to return standardised unrotated factor scores. Thank you very much, Ursula ==================================================== NFO Infratest Ursula

pca analysis: extract rotated scores?
Dear all I'm unable to find an example of extracting the rotated scores of a principal components analysis. I can do this easily for the un-rotated version. data(mtcars) .PC <- princomp(~am+carb+cyl+disp+drat+gear+hp+mpg, cor=TRUE, data=mtcars) unclass(loadings(.PC)) # component loadings summary(.PC) # proportions of variance mtcars$PC1 <- .PC$scores[,1] # extract un-rotated scores of

strwidth and strheight for rotated text
Dear All, I would like to plot text with a box around it. I used strwidth and strheight to compute the size of the box which is plotted with rect: z <- rnorm(10) # horizontal text works plot(rnorm(10)) x1 <- 5 y1 <- 0 label <- "Label" cha <- paste(" ", label, " ", sep = "") xh <- strwidth(cha, cex = par("cex")) yh <-

trying to rotate barplot labels
hi everyone : i'm trying to rotate the x axis labels in my barlot ( yes, since yesterday ) and my prob12matrix is 2 rows and 16 columns and i followed the instructions in the archive "rotate barplot labels". i was really looking forward to seeing my labels turned but the plot just came back with no labels ? can anyone see what might be going on ? it worked when i followed the

No subject
Hello, I'm doing a pca analysis and get unrotated PCA results (using "pca"). I then used "varimax" to rotate the PCs, vload <- varimax(cproj,normalize=TRUE,eps=1e-5) #cproj is the "loadings" from "pca" and calculate the score coefficients with: coef <- solve(correlation matrix of original data) %*% (vload$loadings) Then calculate the

Help with Varimax (mva)
I am using R mainly for multiple linear regression and principal components analyses and I am quite happy with it. I think it is a worderful work you have done. But I am having a problem when using Varimax for rotating loadings obtaines from a princomp (I use the cor = TRUE option): the variance across the components in the variables does not mantain. Let me explain it with an example in which

It may depend on which decomposition method you are using, princomp uses eigen whereas prcomp use svd.

Checked mongrel_rails_service drafts
Ok, I have checked in the first draft of rails win32 service into examples mongrel_rails_service is the controller, and the _svc script is actually the service. The controller uses Mongrel Commands as requested by Zed, but the service was simplified for debugging purposes, later will merge and refactor both files. The environment defaults to production, so if wanted to run it on other, you must

Problem with PCA
I have an exercise. With 3 kinds of yohourt a,b,c. There are 25 participatients estimate 3 norms: taste (va,vb,vc), structure (ca,cb,cc) and price (ga,gb,gc) and give the mark from 1 to 5.
