parsing - Lex- and YACC-like tools for R? -


do such parsing tools exist r? not have lex / yacc compatible tool case.

(i'm r newbie)

edit: i'm interested in implementing language using r.

afaik, there no parser generator r.

however, user created packages in r (a.k.a. "extensions") can written in java, c or fortran (and r, of course). so, use lex/yacc , bison (in case of c) or javacc or antlr (for java) create lexer , parser language , use in r code.
