It works for me on intel. Check out the Keyboard and Console HOWTO since
I did pretty much everything they suggested, including:
.inputrc:
"\C-?":delete-char
"\C-h":backward-delete-char
.bashrc:
stty erase ^h
.Xresources
*VT100*backarrowKey: true
/etc/keyboard/default.map:
key 14 = Backspace
key 111 = Delete
I have no idea anymore which of these incantations is required, and it
probably depends on which system you are running. Also, I may have
missed a couple.

Which sounds exactly like the problem I had. It seems table.read()
returns a list, and Dat[correct_subscript] is a list of one element
that element being the vector of interest. Try using instead
Dat[[correct_subscript]] which returns the single element rather
than the whole list.
