title: R-exams: How to change margins in exams2nops()?
body: <p>I would like to prepare an exam using exams2nops() function. However, I want to change margins in a questions section. I tried to modify the header argument in the exams2nops function to:
  <code>exams2nops(...header = &quot;\\usepackage[margin=1cm]{geometry}&quot;...)</code>
  however it only had an effect on a first page.  I do not know how to solve that issue.</p>
