R/exams: prevent page breaks between two paragraphs in exams2nops

I am currently working with the R/exams package, specifically creating exams using the exams2nops function and the order of the questions is randomized. Everything works fine except for one detail: The samepage = TRUE option only prevents page breaks within a paragraph. For my purpose it is however necessary not to split any of the exercises. Within one text it would still be possible to write only one paragraph (although this is not helpful for clarity). Unfortunately, whenever I need to include a table, I am forced to start a new paragraph which is not "protected" against page break. Due to the randomization there are always some copies where text and tables are splitted to multiple pages. I tried .Rmd as well as .Rnw files and also tried to integrate some LaTeX functions such as \nopagebreak and \needspace without success. So far, I am not too experienced with LaTeX and also with Google's help I did not find a solution.

Here is a minimal example of what kind of exercises I am talking about:

I am not sure what to try.

Solution

The samepage = TRUE option only enforces that the {answerlist} is in a {samepage} environment - but not the entire {question}.

The easiest option to accomplish what you want to do seems to be to re-define the {question} environment in the header = argument. You could either try to put everything into a {samepage} environment via

exams2nops(...,
  header = "\\renewenvironment{question}{\\item \\begin{samepage}}{\\end{samepage}}")

This may have to be coupled, though, with some \nopagebreak commands in between paragraphs. (See: Make an unbreakable block in TeX)

A simpler solution might be to put every exercise on its own page by including a page break at the end of each exercise:

exams2nops(...,
  header = "\\renewenvironment{question}{\\item}{\\newpage}")

In case you are not familiar with the LaTeX syntax above:

\renewenvironment{foo}{...}{...} re-defines the environment "foo".
The first ... is what is executed at the beginning of the environment.
The second ... is executed at the end.
By default, only \item is executed at the beginning to increase the enumerated counter for the exercises.
The double backslashes (e.g., \\item) are required in R to escape the backslashes as they are a special character.
