similar to: Capturing error messages while running R through an external program

I am using 32 bit R - 2.15.2 version and working on package ltm. The program does not give me any warning message when I run tpm command for a dataset. If run tpm command for the same dataset in 64-bit R 2.15.1 version, I get the warning message shown below. Can someone suggest why is no warning message being generated by 32-bit R? Or is it being generated but not getting printed? Which function

I am fitting 3 parameter model to my response matrix and want to generate item characterstic curve. I want to specify file name to save item characterstic curve by passing it as external parameter to the R batch script. The following is the code I have written for this. *R Script:* library(ltm) cmd_args = commandArgs(); for (arg in cmd_args) cat(" ", arg, "\n",

Dear R-users, I'd like to announce the release of the new version of package `ltm' (i.e., ltm_0.8-0 soon available from CRAN) for Item Response Theory analyses. This package provides a flexible framework for analyzing dichotomous and polytomous data under IRT, including the Rasch model, the Two-Parameter Logistic model, Birnbaum's Three-Parameter model, the Latent Trait model

Hi Xavier, the reason you observe this feature is that in the 'constraint' argument you should specify the values under the additive parameterization, i.e., when in the second column of the matrix supplied in 'constraint' you specify 2, then you need to provide the easiness parameters (not the difficulty parameters) in the third column. Check the Details section of ?tpm() and

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

Hello to All Members of this Group, Can I get the Test Vectors in .wav format for different sampling rates in order to Test the Ogg Vorbis Encoder Code ? If possible Forward the Link where I can get effective testvectors to Test the Encoder. Please Reply As soon as possible .

Hello forum, I have developed an IRT model for a set of items on a large reference sample. I now want to use the IRT parameters that were estimated in the reference sample to score new individuals, one at a time. What R package(s) would allow me to do this? Also, several covariates were associated with item thresholds in the reference sample, so I was wondering if any programs can take

An updated version of the package plink has been uploaded to CRAN. This is a major revision that now includes multidimensional models and methods. plink is a package for conducting unidimensional and multidimensional IRT-based test linking using separate calibration methods for multiple groups for single-format or mixed-format common items. The package supports sixteen IRT models and eleven

Dear all, I am trying to optimize a logistic function using optim, inside the following functions: #Estimating a and b from thetas and outcomes by ML IRT.estimate.abFromThetaX <- function(t, X, inits, lw=c(-Inf,-Inf), up=rep(Inf,2)){ optRes <- optim(inits, method="L-BFGS-B", fn=IRT.llZetaLambdaCorrNan, gr=IRT.gradZL, lower=lw, upper=up, t=t, X=X)

The function factor.scores is used with package ltm and others to estimate IRT type scores for various models. It inherits objects of class grm, gpcm and a few others. What I would like to do is to use the factor.scores function, but feed it my own item parameters (from a bifactor model where the 2PL parameters are adjusted for the bifactor structure). Does anybody have an idea of how this might

I have a continuous loop running in an external library that I am calling from C (R API). This loop is processing events in real time with the possibility of significant lag between events. When processing an event, I can make use of R_CheckUserInterrupt, but while the external library code is waiting on a new event, I don't have an opportunity to call this - my entry points are only on

I have been struggling with the same problem for the past few hours and am desperately in need of some help.

Hi, I've a DID number that gets passed to three internal phones and a cell phone via my outbound IAX trunk. If the cell phone is off or out of coverage, its voice mail captures the call. What's the best way to avoid this? Is there a recommended way to force the cell phone user to press 1 before the call is passed there ala google voice? Or is there another way to detect the presence of
