[Rd] Creating a Factor Object in C code?

Hi guys I am currently working on a small bit of bridging code between a database system and R. The database system has the concept of varchars, a la factors in R, as distinct from plain character strings. What I would like to do is when I receive a list of character strings from the remote dat

[Rd] Suggestion: 'method' slot for expand.grid() (incl. diffs)

Dear expeRts, The order in which the variables vary in expand.grid() is often unintuitive. I would like to suggest a 'method' slot for expand.grid() which requires only very little changes (100% backward compatible) and which allows one to control this order. Please find attached diffs against R-d
