This is one option but you likely can set up a custom interface that is easier to use. If you use the xexams() workhorse function directly you can do something like this:

## get one random version of a single-choice exercise
set.seed(0)
x <- xexams("deriv2.Rnw")

## use the first (and only) random version of the first (and only) exercise
x <- x[[1]][[1]]

## extract the question and questionlist

x$question
## [1] "What is the derivative of $f(x) = x^{7} e^{2.3x}$, evaluated at $x = 0.66$?"
## [2] ""
x$questionlist
## [1] "$2.89$" "$4.72$" "$3.21$" "$5.27$" "$2.64$"

Similarly, you can extract the $solution and $solutionlist.

If your exercises are not in .Rnw but in .Rmd format, then you additionally need to convert all text from Markdown to LaTeX. You can do so via:

textrafo <- make_exercise_transform_pandoc(to = "latex", base64 = FALSE)
set.seed(0)
x <- xexams("deriv2.Rmd", driver = list(sweave = NULL, read = NULL, transform = textrafo, write = NULL))

Some more details on how to work with xexams() are provided in the answer to this SO question: https://stackoverflow.com/questions/62315622/

It seems like `exams2pandoc(..., type="latex")` does the trick

Hi, I need to include some examples of exam questions in a larger latex document in the form exams would render them. Is there a way to keep the latex source with exams2pdf or any alternative? Thanks and Happy New year!
