Minor changes

• add table9 as a variant of tidyr::table2 as a 3-dimensional array (xtabs).
• improved capitalize() to also work for character vectors (i.e., setting the case of each element to upper- or lowercase).

Details

• fix minor bugs.

ds4psy version 0.7.0

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

ds4psy version 0.6.0

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

ds4psy version 0.5.0

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).
