[R] The end of Matlab

I just realized that my idea of doing something without going into the 
extraction functions itself won't work 
:-( it was a nice dream, though.

The reason is that there is no general way to find out what the needed length 
is: At least I'm just writing a class where 2 kinds of columns are involved. I 
don't give a dim attribute, though. But I could, and then: how to know how it 
should be interpreted?

nothing would break if some other sign instead of : would be used. Maybe 
something like "end"...

This might be true in any case.

If I only think of how many lines of nrow, ncol, length & Co I could have 
written instead of posting wrong proposals....
