[R] dataframe behavior

[Martin Henry H. Stevens]

Thanks for the prompting. I used unclass(belle) and found all kinds of wacky
attributes including rownames associated different variables. Although
class(belle) returned 'data.frame' is was sufficiently screwed up to behave
in an unusual manner.
My rather inelegant solution was:

 bm <- data.frame(matrix(as.numeric(as.matrix(belle)),nrow=48))
names(bdf) <- names(belle)
