问题 We think about distributing an open-book exam as a fillable PDF form via exams2nops . The idea is that students do not print the PDF and mark their answers with a pen, but rather fill in their answers electronically in their PDF (e.g. with Acrobat Reader), and send back that PDF to us (or upload it via Moodle). Then, the PDF is "scanned" / the answers are extracted from the PDF. Currently, the checkboxes for MC/SC answers are not clickable; also the textfields for free text answers could be

问题 When I try to generate the exams' solution with the exams2nops(...template="solution"...) I get the following error message: Error in exams2pdf(file, n = n, nsamp = nsamp, dir = dir, name = name, : formal argument "template" matched by multiple actual arguments How can I produce an exams' solution with the exams2nops ? 回答1: You cannot do that in one go, you need two runs after setting the same seed, e.g., set.seed(1) exams2nops(my_exam) set.seed(1) exams2pdf(my_exam, template = "my_solution

问题 I'm using the latest version of R/Exams. When I export questions to Blackboard ( exams2blackboard ) in a ZIP file, then import the ZIP file into Blackboard in the "Test" page (to build a test) or the "Pool" page (to build a pool), each question is imported into its own individual pool, rather than all in a single pool. I must then create a new pool and manually copy each question from its own pool to the new pool, then delete the single-question pools one by one. It's very inconvenient and

问题 I'm completely new to R and R/Exams. I have installed R and R/Exams, and tested the dist example to generate HTML outputs. When I tried to generate PDF outputs, R/Exams always used tinytex and failed because Sweave.sty was not found. I already have TeXLive installed on my system and use LaTeX regularly in my work. I have resolved the problem with Sweave.sty being not found by adding the R's texmf to my TeXLive. However, I still want to use my TeXLive installation instead of tinytex . Is there

问题 I would like to use your excellent r-exams package to create a paper and pencil exam with automatic grading. I have used exams2nops in the past for a series of schoice and mchoice questions. However, I now need to have an exam with an introduction page where I give a table with data and some outputs from statistical software (say normality tests, Levene, etc... I can generate that with Rmd)and tell a small history about the data and the experiments involved in gathering the data. So My Exam
