Dear all,
I also use matrices inside data.frames in my (S4) class hyperSpec.
So, yes, it would be great if commands like apply would work as straightforward
as e.g. rbind does on such data.frames.
The problem here seems to me different, though:
Is it possible that the relevant difference

Using rbind with Surv objects outside of data.frames shows a similar
Hi,
The following was already a topic on r-help, but after understanding what is
going on, I think it fits better in r-devel.
The problem is this:
When a data.frame has another data.frame in it, rbind doesn't work well.
Here is an example:
--
a=data.frame(x=1:10,y=1:10)
b=data.frame(z=1:10)
