The GroupE function allocates data in column into existing groups. To use this command you first need to decide your own groups and place them into the target column. Secondly you need to set the target column to be a group column and the next column to be a frequency column.
Any data that cannot be allocated to an existing group will be allocated to an "other" group appended to your existing groups.
As shown in the example, the groups do not necessarily need to be a constant width and gaps are allowable.
Example: GroupE(A)
