[R] warnng to an error....

[Bert Gunter]

What is class(x) ??

I think you need to (re?) learn about S3 classes, which can in general be
vectors. See ?class (the S3 portion) or any tutorial on S3 classes in R. I
have no idea what you are trying to do, but I *suspect* it may be
accomplished through S3 inheritance rather than changing the class vector.
That is just a guess, however.
