That format is proprietary to SAS. You would need:
1. A licensed copy of SAS available (which is called from read.ssd())
and the lack of which results in the error above. Note the 'sascmd'
argument in read.ssd():
character string giving full path to SAS executable.
2. A third party conversion application (such as DBMS/Copy) which can
read the proprietary SAS dataset and export it to a format that can be
read by R, such as a CSV file.
If the entity that provided you with the SAS dataset can export it to an
alternative format, that would be helpful. There are also functions
available in R which can read the so-called SAS Transport format (which
is openly defined). These would include:
read.xport() in foreign
sasxport.get() in Hmisc, which uses the former
You may wish to search the r-help archives as I recall issues with the
use of the above functions that may require some further insights.
