Hello all

I am manipulating some data and wish to expand/unmerge (i.e. do the opposite of aggregate) rows in a data matrix based on the values in a particular column and a seperator, e.g.

Col1	Col2
n1;n2	6

...separating by ";" becomes....

Col1	Col2
num1	6
num2	6

Any ideas?

Also can I do this based on values in two columns?  EG:

Col1	Col2	Col3
n1;n2	ID1;ID2	6


Col1	Col2	Col3
n1	ID1	6
n2	ID2	6
