Wow, did I stump everyone with this? Mostly I'd just like to build
a class without getting the error below.
Hardly.
a) LHS= left hand side
b) It is not an error message in the first place, and for another
thing, why are you creating instances of a class with the same name
as the class?
( You probably need to look at the documentation for new(). )
Cheers!

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?)...
Cheers!

"[W]hen people thought the earth was flat, they were wrong. When
people thought the earth was spherical, they were wrong. But if you
think that thinking the earth is spherical is just as wrong as
thinking the earth is flat, then your view is wronger than both of
them put together."
