is.prob

is_prob_interval

is_prob

in_range

Checks if <code>x</code> is in an opened or closed interval between <code>min</code> and <code>max</code>.
The default is set as such, that the chosen interval is an interval of \((0,1)\).
For example, in the case of <code>x</code> being a probability.

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'.
