This repository contains the datasets and the R code used in Martinkova and Hladka's "Computational aspects of psychometric methods. With R. (In preparation)"
The R code is separated by chapters. Code for installation of necessary R libraries is included in the InstallPackages.R file. Code for each chapter includes lines for loading the packages needed in that chapter.
Datasets are stored in folders. The .csv files may be used in the interactive ShinyItemAnalysis application. The .Rda and .Rdata files may be used in the R code. Each folder/dataset includes a breef description.
All the files may be downloaded as a .zip file by clicking Code and then clicking Download ZIP. Alternatively, individual chapters can be downloaded separately by clicking on the name of the R file, then clicking the Raw button, and finally saving that page as a .R file.
