Release of ds4psy (0.7.0) on CRAN adds functionality, increases modularity, and fixes a bug in text data. [2021-05-12]

Changes since last release:

Major changes

• Breaking change: The function read_ascii() was split into 2 parts (to enable independent access to their functionality):

  1. A new read_ascii() version reads text (from file or user input) into a character string;
  2. A new map_text_coord() function converts a text string into a table of individual characters (with x/y-coordinates).

• Added plot_chars() for plotting characters of text and visualizing pattern matches (specified as regular expressions) by highlighting labels (color/angle) or background tiles (color). The function uses 2 auxiliary functions:

  1. map_text_regex() adds pattern matching options (for colors and angles) to map_text_coord().
  2. plot_charmap() plots character maps as text and tile plots (with aesthetics for labels and tiles).

• Added count_chars_words() for counting the frequency of both characters and words in text strings.

Minor changes

• added plot_mar argument to theme_empty()
• added functionality to plot_text() (but see plot_chars())
• added utility functions for locating, identifying, and assigning vectors (of color/angle maps) to text strings matching a pattern
• added text_to_chars() and related functions for converting character strings (e.g., text to characters, preserving spaces)
• added utility functions for counting the frequency of characters and words in text strings
• renamed is_vector() to is_vect() as is_vector() function is defined by the purrr package

Details

• signal deprecation status in plot_text()
• bug fix: removed marked UTF-8 strings from Trumpisms

Release of ds4psy (0.6.0) on CRAN adds functionality, updates data, and reduces dependencies. [2021-04-08]

Changes since last release:

Major changes

• added is_vector() to check for vectors (i.e., atomic vectors or lists)
• added get_set() for motivating visualizations

Minor changes

• updated data in fame and Trumpisms

Details

• removed import of cowplot by adding theme_empty()
• reduced reliance on unikn by replacing some colors with corresponding HEX codes

Release of ds4psy (0.5.0) on CRAN: https://CRAN.R-project.org/package=ds4psy. [2020-09-01]

This release mostly provides additional functions for dates and times:

• added diff_dates() to compute temporal differences between dates (in human time units of years, months, and days)
• added diff_times() to compute temporal differences between times (in human time units of years, ..., and seconds)
• added diff_tz() to compute time difference based on time zone differences
• added days_in_month() to obtain number of days in months for given dates (accounting for leap years)

Minor changes include:

• added is_equal() and num_equal() to check pairwise (near) equality of vectors
• added theme_clean() as an alternative to theme_ds4psy()
• renamed is.wholenumber() to is_wholenumber()
• revised arguments of sample_date() and sample_time() to align with sample()
• revised theme_ds4psy() to provide control over colors of backgrounds, lines, and text elements
• updated fame data

Plus some bug fixes (see NEWS.md).

Release of ds4psy (0.4.0) on CRAN: https://CRAN.R-project.org/package=ds4psy. [2020-07-06]

This version adds support for processing data with dates and times:

• simple date and time functions now include options for returning dates or times, rather than strings
• added time zone support to various functions
• added datasets with date and time variables

Release of ds4psy (0.3.0) on CRAN: https://CRAN.R-project.org/package=ds4psy. [2020-06-15]

This release adds support for text processing.

The current version of the textbook Data Science for Psychologists is still available at https://bookdown.org/hneth/ds4psy/.

A new release of ds4psy (version 0.2.1) is available on CRAN: https://CRAN.R-project.org/package=ds4psy. [2020-05-06]

This is a maintenance release to remove some dependencies, fix bugs on CRAN platforms, and add some datasets.

An updated version of the textbook Data Science for Psychologists is still available at https://bookdown.org/hneth/ds4psy/.

A new version 0.2.0 of ds4psy has been released on CRAN on 2020-04-19. This release adds functionality (mostly new data and functions) and fixes some bugs (see NEWS file for details).

This version of the R package ds4psy supports the 2020 version of the textbook Data Science for Psychologists available at https://bookdown.org/hneth/ds4psy/.

The R package ds4psy was released on CRAN on August 10, 2019.

The initial version of the package contains all data sets required for the examples and exercises in the book Data Science for Psychologists, which is freely available at https://bookdown.org/hneth/ds4psy/.

The book and course introduce principles and methods of data science to students of psychology and other biological or social sciences. The ds4psy package primarily provides datasets, but also functions for graphics and text-manipulation that are used in the book and its exercises.
