dbreaks

Creates a number of equidistant or non-equidistant breaks for given data <code>x</code>.
If <code>width</code> is not given then it will be set to <code>diff(pretty(x))[1]</code>.
<code>probs</code> can either be a single integer, giving the number of quantiles, or a vector of probabilities with values in \([0,1]\).
Please note that if <code>width</code> is too large, then using <code>probs</code> may result in equidistant breaks too.

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'.
