[R] weird error: Coercing LHS to a list

Hi all! I'm trying to build a simple class, but I'm getting a weird error.

E.g. if I do:

gregion = setClass("gregion", contains = "data.frame", representation(name = "character", poly.x = "numeric", poly.y = "numeric" ))

gregion$name = "North America"

Then I get this message:

Warning message:
In gregion$name = "North America" : Coercing LHS to a list

...although it appears to work, I'd rather not have disturbing mysterious error messages (what's LHS?)...
