I'm looking for a package that would take a mathematical function written in symbolic notation and convert it into R code.

What I have in mind would be something like the following:

1) Have a GUI (e.g. something like Microsoft Word equation editor, but computer readable) to produce an equation so that it would look just like it would if you were writing it on paper

2) Have some way to translate the GUI into some markup language (perhaps this would be in a non-R application)

3) Have code that translates the markup into an R function.

My motivation is that I teach an intro stats class that uses randomization techniques. I would like for the students to be able to make up their own statistics and then simulate null distributions or estimate bootstrap confidence intervals using them. I'd prefer to make it as easy as possible for them to enter the formula for their statistics into the computer, and I think that will be easier if it looks from their end just like it would if they were writing it on paper. After they submit the equation, I would have an RStudio shiny applet take care of the rest.

Any suggestions for R packages that could do this or pieces of it would be very much appreciated.

Thanks,
Scott
