All, I have several years of longitudinal test scores for students (many who switch schools at various points in time). I am using a mixed-effects model with crossed random effects to model student trajectories. The model includes time at level 1 and students crossed with schools at level 2. When I run the model I get the posterior variances on the intercepts and slopes for students and schools,

All, I recently made some changes to my package and ran R CMD check, but I am getting a warning regarding my data sets. I am running R 2.6.1 I have an image (.RData) file containing five data sets in the data subdirectory and an .Rd file for each of the data sets in the man subdirectory. When I run the check I get the warning "Data sets with usage in documentation object <dataset

The first version of the package plink has been uploaded to CRAN. plink is a package for conducting unidimensional IRT scaling and chain linking for multiple groups for single-format or mixed-format common items. The package supports eight IRT models and four calibration methods. Dichotomous Models: 1PL, 2PL, 3PL Polytomous Models: -Graded response model -Partial credit model -Generalized

I have a really long functions, and at the end of the function, I am using a if statement to tag certain keywords based on whether they have certain values contained in them. However, the if statement doesn't seem to work. When I had split up the commands into various functions, it worked fine, but I'm not sure what going on now that it's combined into a single function. myfunc

Hello everybody, If anybody is about to graduate and is looking for a research position, ICL at the University of Tennessee (http://icl.cs.utk.edu) is looking for a compilers person. We are looking for somebody with practical experience in compiler technology and some understanding of linear algebra. Sorry for spamming the list with non-development content, but I hope a lot of

To Whom it May Concern: I have been using R version 2.6.2 for awhile now, installed on a PowerMac G5 running OS 10.4.11 I typically get Quartz graphics output from R into Adobe Illustrator CS2 simply by copying and pasting. Upon upgrading to R version 2.7.0, I now receive an error from Illustrator when trying to paste R generated graphics from the Quartz window into Illustrator. I do

I cannot seem to get a L'abbe plot to work on R. I do not understand what the X coordinates, or alternatively an object of class metabin, is supposed to mean. What is a class of metabin? Institute of Behavioral Genetics University of Colorado, Boulder Whitney.Melroy at Colorado.EDU

Hi all, Probably a rudimentary question. I have a flat file that looks like this (the real one has ~10e6 elements): 10110100101001011101011 and I want to pull that into R as a vector, but with each digit being it's own element. There are no separators between the digits. How can I accomplish this? Thanks in advance! Matt -- Matthew C Keller Asst. Professor of Psychology University of

Hi, I'm trying to use a similarity matrix (triangular) as input for pam() or fanny() clustering algorithms. The problem is that this algorithms can only accept a dissimilarity matrix, normally generated by daisy(). However, daisy only accept 'data matrix or dataframe. Dissimilarities will be computed between the rows of x'. Is there any way to say to that your data are already a

Hi all, I tried 1.3.0pre4 with ICL on Windows and found some issues. Not sure if this is the right place to submit patches, but someone suggested this on the apparently dead SourceForge patch tracker. The first two are quite straight forward: - The ICL patch fixes a typo in bitmath.h and adds FLAC__bitwriter_write_zeroes to the external declarations in bitwriter.c. - The Ogg patch replaces

Hi all, Is there a way to skip non-sequential lines using the "skip" argument in the scan function? E.g., I have a matrix with 100 rows and 1e7 columns. I open a connection and want to read only lines 5, 7, 9, etc [i.e., seq(5,99,2)] It might seem that the syntax to do this would be something like this (if only the "skip" allowed vectors in the same way colClasses does in

Hi all, My graduate student is logging onto my macpro and running R through ESS aquamacs (with Mx ssh and then Mx ess-remote). Everything is working fine until we get to graphing. We are trying to give him the ability to look at graphics interactively. The ESS manual is not too helpful: "If you run X11 (See Section 13.3.2 [X11], page 68, X-windows) on both the local and remote machines

Hi all, I'm having trouble getting access to the pwr. This is on Ubuntu Lucid Lynx, 64 bit. I'm installing pwr via packages.install('pwr'), and loading it via library(pwr), both of which appear successful. Strangely, I never get access to the pwr object in R. I tried installing it to /usr/local/lib/R/site-library and ~/R/x86_64-pc-linux-gnu-library. I also tried installing it

Hi all, For computational reasons, I need to estimate an 18x18 polychoric correlation matrix two variables at a time (rather than trying to estimate them all simultaneously using ML). The resulting polychoric correlation matrix I am getting is non-positive definite, which is problematic because I'm using this matrix later on as if it were a legitimately estimated correlation matrix (in order

Dear friends, I have two questions regarding the use of lattice. First some code: ## begin code z <- cbind(rep(c("BIC", "ICL", "s_v", "Q_v", "sig-q", "s_lsk", "s_lML", "s_mlsk", "s_mlML", "s_la8", "s_haar"), each = 250), rep(c(5, 10, 20, 30, 50), each = 50)) z

Dear All - I would like to make multi-page plots, but my plots are writing over one another - thus leaving just the last plot. Here is what I am doing: pollutionRose(temp, "nox", type="hour") update(trellis.last.object(), layout =c(3,3,3) ) I would like 24 plots with 9 plots/page (the last page would not have 9 plots) Is there any way to "force" layout to make 3

Can anyone help me? I''m having problems with the following code where I want to test the null hypothesis that regression slopes are the same among regressions. Here''s the code I''ve written with comments that include the final error I get. ... initial.dir <- getwd() library(systemfit) library(multcomp) basdata <- read.table("data_into7_test.txt",

Dear all, I'd like to use R to read in data from the web. I need some help finding an efficient way to strip the HTML tags and reformat the data as a data.frame to analyze in R. I'm currently using readLines() to read in the HTML code and then grep() to isolate the block of HTML code I want from each page, but this may not be the best approach. A short example: x1 <- readLines("
