SAS code for storing final results in a file and retrieving without going through all steps

ak2011 — Sun, 15 Mar 2020 02:30:50 GMT

Hello,

I would appreciate if someone could help me with the SAS code for storing final results at a file and retrieving the information directly from the stored dataset and using it without going through all the several steps.

Please find below this dataset and the SAS procedures used to arrive at the final dataset t2b.

Eg. if I complete work today and write final results to dataset t2b. Is there a code to directly obtain the stored information and use to for for say logistic regression without going though all the many steps?

Next time,I wish to start work directly form dataset t2b and not to run entire work again

Re: SAS code for storing final results in a file and retrieving without going through all steps

To keep results you need use your own assigned library.

Define a final library by

libname <final libref> <path to a folder>;   /* final library reference name */

then use it:

1) to keep the created formats by

proc format lib=<final libref> ;
   ... your code ...
run;

2) creating final data sets:

data <final libref>.<dataset name>;
    ...any code ...
run;

If you have any issue, post the log using the {i} icon on top this window.

You can address table names in the form <libref>.<table name>

If you only use the table name in your code then SAS uses WORK as libref: WORK.<table name>

WORK is a location on your disk which SAS removes when you terminate a SAS session.

You can define a libname (or use an existing one) to define the path to a folder (on the SAS server side) where you want to store your SAS tables permanently. You then use this libref so the table doesn't get created in WORK but in the folder the libref points to.

At begin of a new SAS session just issue the libname statement again. This gives you access to all SAS tables created under this folder in earlier sessions.

libname mydata '<path to folder>';

proc freq data=mydata.t2b;
  tables cla_exp bio_exp amo_exp chl_exp;
  Title "Unique ids frequecies for cla, bio, amo and chl";
run;
