Commands
SetYReplicates [#]
ClearTable <row>,<col>,<subcol>
DeleteAllDataSets <CLEAR>
Explanation
Using a script, you have limited ability to change a data table.
The SetYReplicates command changes the number of Y replicates (subcolumns), but script commands can not make other changes to the data table or number (decimal) format.
The DeleteAllDataSets command deletes all data and all links to analyses and graphs.
The ClearTable command erases all data to the left and below of the designated cell (including the cell itself) but maintains links to analyses and graphs.
