Is it possible to use data frame in r-exams?

I would like to paste the data-frame from the R environment to the latex part (question or solution part) when creating exercises in r-exams. Later the exercises will be imported into Moodle. Is that possible in r-exams? We saw it is possible when the object is matrix object via `$\Sexpr{toLatex(matrix_obj)}$`. But a similar way does not seem to work with the data-frames. Thank you!
