Statscraft 0.7.0, release v0.7.0

ADD FILES

Append the cases of several data files, matching variables by name.

Syntax

ADD FILES /FILE=* | 'path' | dataset [/RENAME=(old = new) ...] [/IN=var]
          /FILE=... [/RENAME=...] [/IN=var] [/BY varlist] [/FIRST=var] [/LAST=var]
          [/MAP] [/KEEP=varlist] [/DROP=varlist].
FILE=* is the active dataset; a dataset name (DATASET NAME), quoted or not, is that open
dataset and comes before a file of the same name. A variable missing from a file is blank in its cases.
The first file that has a variable gives its format and measurement level; a later file
fills in a label, value labels or missing values the earlier ones lack. A string variable
takes its widest width; a variable that is numeric in one file and a string in another is
an error. BY interleaves files sorted by the key variables.
RENAME and IN follow their FILE; BY, FIRST, LAST, MAP, KEEP and DROP follow every FILE.
IN adds a variable that is 1 for the cases from that file, else 0. FIRST and LAST (with
BY) add one that is 1 for the first or the last case of each key. These are F1.0 and go
at the end, IN first; KEEP and DROP cannot name them. MAP lists the variables of the
result at that point with their names in each file.
The result has the documents of every file. It stays weighted only when every file is
weighted by the same variable; otherwise a warning says so.

Example

ADD FILES /FILE=* /FILE='wave2.sav' /RENAME=(q1_new = q1) /DROP=tmp.

statscraft help ADD FILES prints the same text in the terminal. All commands
