Andrie noticed that first, and I can confirm: from our end, it looks as if the backend to http://cran.r-project.org/submit.html is currently down. Dirk -- http://dirk.eddelbuettel.com | @eddelbuettel | edd at debian.org

Hello! I would like to draw a graph like the following: http://www.optics.rochester.edu/workgroups/cml/opt307/spr04/pavel/plot_small.jpg Aim is to plot confidence intervals of treatments for X(=response1) and Y(=response2) axis simultaneously to visualize aggreement of confidence interval for two responses. Can anyone please provide me some direction to start with? Thanks! -- Kim.

Dear R help I have conducted a fa() analysis, and I want to use fa.diagram to assess the extent to which the 11 latent factors predict the 37 items in a psychological battery. However, the display on the screen has very large font size for the coefficients of the relationship between the 11 factors and the 37 items, so the numbers overlap and are therefore illegible. When I output this to a

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

Hello, I searched the archives but found no answers. How to modify the hisgram color of function pairs.panels of Psych package ? I tried col() but it was the line color modified. Thanks. Elaine [[alternative HTML version deleted]]

I have a quick statistical question and hoped somebody has a tip for me without me having to go to the local statistician on Monday. I assess 4 statements from 90 subjects. Each of the 4 statements receives one of three responses (say -1, 0, or 1). I can use Cramer's V or Spearman correlations to assess the correlation between each pair of statements, but I am looking for a measure of

Hello, I wonder whether binary (rooted) trees with simple labels (say, integers) can be drawn by some R-package? Couldn't find one. Just to make sure (since "trees" can be many things): I mean those computer-science creatures, with roots and subtrees. Thanks for your consideration in any case Oliver P.S. Perhaps there is some graph-drawing package? (Here a "graph"

Dear R users, I would like to know if it is possible to calculate the Mean Error (ME), the Root Mean-squared error (RMSE) and absolute error (MAE) for two temporal series of directional data. Where Can I get documentation about it? Thanks in advance [[alternative HTML version deleted]]

Dear all, I can't get the labels slot in ICLUST to accept a character vector. library(psych) test.data <- Harman74.cor$cov ic.out <- ICLUST(test.data,nclusters =4,labels=letters[1:ncol(test.data)]) ##?Error in !labels : invalid argument type ic.out <- ICLUST(test.data,nclusters =4,labels=1:ncol(test.data)) ## OK Any ideas?

Hello, I am a complete beginner to R. I use a mac and want to import and read a .csv dataset stored as .csv file. I understand I eventually enter <- read.csv("size.csv", header=T) , but I can't get R to find my file, which is called size.csv and located /Users/davidoconnor/Desktop/Eart-125/size.csv Thank you very much!

Hi all, Are there base functions that do the equivalent of this? fliptb <- function(x) x[nrow(x):1, ] fliplr <- function(x) x[, nrow(x):1] Obviously not hard to implement (although it needs some more checks), just wondering if it had already been implemented.

Haj i try to perform a principal component analysis by using a tetrachoric correlation matrix as data input tetra <- tetrachoric (image_na, correct=TRUE) t_matrix <- tetra$rho pca.tetra <- principal(t_matrix, nfactors = 10, n.obs = nrow(image_na), rotate="varimax", scores=TRUE) the problem i have is to compute the individual factor scores from the pca. the code runs perfect
