I have been using r/exams in some of my last exams and everything has worked fine. This semester, however, r/exams seems to generate the exams in Times New Roman instead of Helvetica, which messes with the character recognition in the scanning process.
Even the minimal example, produces this behavior:
library("exams")
myexam <- list("cholesky.Rnw")
set.seed(403)
ex1 <- exams2nops(myexam, n = 1,
dir = "nops_pdf", name = "demo", date = "2015-07-29",
points = c(1), showpoints = TRUE)
Does anyone have any idea what could have gone wrong? How do I see the intermediate steps? I get no error messages.
Thanks!

I don't know the package, but there are a lot of options in?exams2nops, have you pored over this? A quick glance shows: "Note that the font in the PDF must not be modified for the reading step to work reliably. (A sans-serif font is used and hence the codesfmath LaTeX package is also used - if it is installed.)", perhaps your latex installation is missingsfmath?

Thanks for the hint. Something was missing in my TinyTex installation. It was not sfmath. I moved to MacTex and it works again!

Starting from R/exams version 2.3-2 (the current CRAN version at the time of writing) it is enforced that the digits that need to be scanned are always in Helvetica (fontfamilyphv) even if the font is switched for the rest of the document.
I'm not sure though which package might have been the culprit in switching the fonts for you when using TinyTex. But I guess it would be useful to find out if others encounter the same problem.
I just went through the source code of exams2nops() to check what packages we use. Partly for historical reasons there are quite a few. Possibly these could also be streamlined.
- Basic tools: graphicx, color, amsmath, amssymb, latexsym.
- For compatibility with
Sweave: verbatim, url, fancyvrb, ae. - Layout etc.: multicol, a4wide, pdfpages, chngpage.
- For compatibility with LaTeX produced by
pandocfrom Markdown: booktabs, longtable, eurosym, textcomp.
