[Rd] Possible bug in 'new()' for Reference Classes

Dear list,

I think I stumbled across a little bug with respect to the standard initialization routine for Reference Classes.

It seems that a field 'self' is treated as if it's name would be '.self' (which we know is reserved for the self reference of the instantiated object itself) and thus an error is thrown. If the field value is assigned in an explicit call after the instantiation via 'new()', everything works just fine:


             self="character", super="character", sub="character"
     new("ClassInfo", self="B", super="A", sub="C")    # Error

     x <- new("ClassInfo", super="A", sub="C")
     x$self <- "B" # Works

Best regards,
