xptread - Create dataset array from data stored in a SAS XPORT format file
Syntax
data = xptread
data = xptread(filename)
[data,missing] = xptread(filename)
xptread(...,'ReadObsNames',true)
Description
data = xptread displays a dialog box for
selecting a file, then reads data from the file into a dataset array.
The file must be in the SAS XPORT format.
data = xptread(filename) retrieves data
from a SAS XPORT format file filename.
The XPORT format allows for 28 missing data types,
represented in the file by an upper case letter, '.' or '_'. xptread converts
All missing data to NaN values in data.
However, if you need the specific missing types then you can recover
this information by specifying a second output.
[data,missing] = xptread(filename) returns
a nominal array, missing, of the same size as data containing
the missing data type information from the xport format
file. The entries are undefined for values that are not present and
are one of '.', '_', 'A',...,'Z' for
missing values.
xptread(...,'ReadObsNames',true) treats
the first variable in the file as observation names. The default value
is false.
xptread only supports single data sets per
file.
Examples
Read in a SAS XPORT format dataset:
data = xptread('sample.xpt')
