Description Usage Arguments Value

Drops columns in the target data.frame (resp) not in the variable name list (items). Adds columns (with NA entries) for entries in the items that are not alrady in resp. This is mainly to simplify using item parameters obtained from one sample (e.g., calibration sample) with a second sample that may not use all of the items.
