This repository contains the R code and the datasets used in Martinkova and Hladka's "Computational aspects of psychometric methods. With R", published with Chapman & Hall / CRC Press in 2023. For more information and materials, see the book webpage: https://www.cs.cas.cz/comps/CAPMbook
The R code is separated by chapters. Code for installation of necessary R libraries is included in the A-InstallPackages.R file. Some introductory code with examples from Appendix are included in the A-IntroductionToR.R file. Code for each chapter (in Ch*.R files) 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.
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.
