Stata's two data types for string and numeric map fairly cleanly onto R's character and numeric. We need:

  • the op_* functions for the factor and interaction operators
  • relational operators (%==%, %>%, %<%, %>=%, %<=%) that implement a bivalent logic
  • logical operators (%&%, %|%, %!%) that do the same
  • confirm that base R's arithmetic operators work as-is without being wrapped
  • subsetting (expressions like x[1] are legal in Stata) - does it work?
  • assignment - does it work?
  • type constructor operators - does the way this is set up now work?
