Welcome to the R package ds4psy — a software companion to the book and course
Data Science for Psychologists.

This R package provides datasets and functions used in the book and course. Its source code is hosted at https://github.com/hneth/ds4psy.

The book and course introduce the principles and methods of data science for students of psychology and other biological or social sciences. The book is available at https://bookdown.org/hneth/ds4psy/.


The ds4psy book and course provide an introduction to data science that is tailored to the needs of psychologists, but is also suitable for students of the humanities and other biological or social sciences. This audience typically has some knowledge of statistics, but rarely an idea how data is prepared and shaped to allow for statistical testing. By using various data types and working with many examples, we teach tools for transforming, summarizing, and visualizing data. By keeping our eyes open for the perils of misleading representations, the book fosters fundamental skills of data literacy and cultivates reproducible research practices that enable and precede any practical use of statistics.

The R package ds4psy primarily provides datasets, but also functions for data generation and manipulation (e.g., of text and time data) and graphics that are used in the book and its exercises. All functions included in ds4psy are designed to be explicit and instructive, rather than efficient or elegant.


The current release of ds4psy is available from CRAN at https://CRAN.R-project.org/package=ds4psy:

install.packages('ds4psy')  # install ds4psy from CRAN client
library('ds4psy')           # load to use the package

The current development version can be installed from its GitHub repository at https://github.com/hneth/ds4psy/:

# install.packages('devtools')  # (if not installed yet)
