gapply

apply_grid

Runs all combinations of elements in <code>...</code> as parameters of <code>FUN</code> (grid apply).
<code>I(.)</code> can be used to avoid that an element is interpreted as a grid value.
If an error occurs, then the result of <code>FUN</code> will not be stored. You may notice missing indices
in the returning list.

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'.
