Dear list A strange bug in the psych package is due to the behavior of the diag function: It gives the expected values for 1, a vector (-1,1), but not for -1 Is this a known feature? > diag(1) [,1] [1,] 1 > diag(c(-1,1)) [,1] [,2] [1,] -1 0 [2,] 0 1 > diag(-1) Error in diag(-1) : invalid 'nrow' value (< 0) Bill William Revelle

Dear fellow developers, Is there an easy way to determine how big my packages (psych and psychTools) will be on various versions of CRAN? I have been running into the dread 'you are bigger than 5 MB" message for some installations of R on CRAN but not others. The particular problem seems to be some of the mac versions (specifically r-oldrel-macos-arm64 and r-release-macos-X64 ) When

Dear friends, How do I stop partial matching of list names? e.g., x <- list(AAAA="aaaaa", BBBBB="bbbbb") is.null(x$A) #returns FALSE even though there is no element A. if(is.null(x$A)) {result <- x$BBBB} else {result <- x$A} result #is aaaa even though there is no x$A element x <- list(CCCC="aaaaa", BBBBB="bbbbb") if(is.null(x$A))

Dear R list, I have discovered a seemingly peculiar feature when using a matrix to index itself (yes, this is strange code, which I have now modified to be more reasonable). #this makes sense s <- matrix(1:3,nrow=1) s[s] #all three elements are shown #but when I try s <- matrix(1:2,nrow=1) s[1] #fine, the first element is shown s[2] #fine, the second element is

Dear friends, I have just gotten a strange error message back from Uwe saying that the most recent version of psych failed to pass R CMD check for Windows. The error message was less than helpful, in that it seems to have failed when trying to include the Rcpp library, which I do not directly call. (see below) "* using log directory

I would say it is a mis-feature. If the 'x' argument of diag() is a vector of length 1, then it creates an identity matrix of that size, instead of creating a 1x1 matrix with the given value: ? diag(3) [,1] [,2] [,3] [1,] 1 0 0 [2,] 0 1 0 [3,] 0 0 1 Of course this makes it cumbersome to use diag() in a package, when you are not sure if the input vector is

This still seems to be the case. I tried uploading the most recent version of psych and got as far as the Step 3 page which says that it has sent out an email. However, although normally this step takes agout 1 minute, nothing has happened for 16 hours. Should we just use the old system of uploading to the ftp site and sending a confirming email? Thanks of course to the CRAN maintainers

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.

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

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

Dear R gurus, There is an interesting problem with accessing specific items in a column of data frame that has incorrectly been given a duplicate name, even though addressing the item by row and column number. Although the column is correctly listed, an item addressed by row and column number gives the item with the correct row and the original not the duplicated column. Here are the

I am trying to simulate a dataset using Parallel Latent CTT model and this is what i have done so far: (START) #Importing psych library for all the simulation related functions library(psych) # Settting the working directory path to C:/NCME path="C:/NCME" setwd(path) #Using the function to generate the data GenData <- congeneric.sim(N=500, loads =

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

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, I am using fleiss kappa for inter rater agreement. Are there any know issues with Fleiss kappa calculation in R? Even when I supply mock data with total agreement among the raters I do not get a kappa value of 1. instead I am getting negative values. I am using the irr package version 0.70 Any help is much appreciated. Thanks and Regards M [[alternative HTML version deleted]]

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.
