The Merge command allows the user to Merge multiple datasets (of the same type), by using both observations and variable names for matching and merging purposes.
If the variables or observations do not match, there is the potential to create missing data with this command.
First, the user must choose which dataset upon which to run the merge command, then the Merge Data window is opened. The user can choose any number of datasets to merge, and can optionally generate a source column to indicate where each variable or observation came from with the merge (in either the design table or annotation table), as well as specifying an output name for the merged dataset.
