Hello everyone,
I have a matrix of over 40000 line and about 30 columns.
For my analysis I would like to add another column with ascending numbers
(column header should be "order", and than 1,2,3,4 ....the end of the
matrix).
During my analysis I reorder them ( due to merge commands by a different
column).
How do I add such a column in an ascending order (or descending for what it
matters)?
THX
Assa
