R packages to make interactive homeworks or exams that you can grade

Dear list members,

I am looking for a way to make interactive homeworks o exams when teaching
statistics in R.

I have been looking on the package gradethis but I do not see how this
package works in the way that I am looking for.

I am looking for something that you can send to the students and the
student send it back to you and you can grade the homework or exam in a an
interactive way.
