dbreaks

Creates a numeric vector of break points for the given data <code>x</code>.
The resulting breaks define bins that are either equidistant (fixed width)
or non-equidistant (quantile-based). If <code>width</code> is not specified, it defaults
to <code>diff(pretty(x))[1]</code>. The <code>probs</code> argument can either be a single
integer, specifying the number of quantiles, or a numeric vector of probabilities
in the interval \([0, 1]\).

The main aim is to further facilitate the creation of exercises based on the package 'exams'
by Grün, B., and Zeileis, A. (2009) <doi:10.18637/jss.v029.i10>. Creating effective student exercises
involves challenges such as creating appropriate data sets and ensuring access to intermediate values
for accurate explanation of solutions. The functionality includes the generation of univariate and
bivariate data including simple time series, functions for theoretical distributions and their approximation,
statistical and mathematical calculations for tasks in basic statistics courses as well as general tasks
such as string manipulation, LaTeX/HTML formatting and the editing of XML task files for 'Moodle'.
