The MSAVE
command evaluates the expression specified just
after the command name, and writes the resulting matrix to a matrix
file (see Matrix Files).
The TYPE
subcommand is required. It specifies the
ROWTYPE_
to write along with this matrix.
The FACTOR
and SPLIT
subcommands are required on the
first MSAVE
if and only if the matrix file has factor or split
variables, respectively. After that, their values are carried along
from one MSAVE
command to the next in syntax order as defaults.
Each one takes an expression that must evaluate to a vector with the
same number of entries as the matrix has factor or split variables,
respectively. Each MSAVE
only writes data for a single
combination of factor and split variables, so many MSAVE
commands (or one inside a loop) may be needed to write a complete set.
The remaining MSAVE
subcommands define the format of the matrix
file. All of the MSAVE
commands within a given matrix program
write to the same matrix file, so these subcommands are only
meaningful on the first MSAVE
command within a matrix program.
(If they are given again on later MSAVE
commands, then they
must have the same values as on the first.)
The OUTFILE
subcommand specifies the name or handle of the
matrix file to be written. Output must go to an external file, not a
data set or the active file.
The VARIABLES
subcommand specifies a comma-separated list of
the names of the continuous variables to be written to the matrix
file. The TO
keyword can be used to define variables named
with consecutive integer suffixes. These names become column names
and names that appear in VARNAME_
in the matrix file.
ROWTYPE_
and VARNAME_
are not allowed on
VARIABLES
. If VARIABLES
is omitted, then PSPP uses
the names COL1
, COL2
, and so on.
The FNAMES
subcommand may be used to supply a comma-separated
list of factor variable names. The default names are FAC1
,
FAC2
, and so on.
The SNAMES
subcommand can supply a comma-separated list of
split variable names. The default names are SPL1
, SPL2
,
and so on.
