Steve,
That makes sense, except that x is a data.frame with about 70
columns. So I don't see how it would convert to a list.
Yeah ... not sure if that's what happening (R class relationships/
testing is still a bit of a mystery to me), but see:
R> df <- data.frame(a=1:10,b=1:10)
R> is(df)
[1] "data.frame" "list" "oldClass" "mpinput" "vector"
But
R> is(df, 'list')
[1] FALSE
So, in short, I don't know if that's what's happening ... did it fix
your problem, tho?
