- Hello, Everyone,
-
- I'm new to this list, and very new in SAS.
-
- 1. I need to read a portable sas data file and save it to a SAS DATA FILE.
- This is a huge file. I actually need 1/4 of the variables only.
- How can I save this subset of data file in this step?
-
- 2. I need to convert CHARACTER variables into NUMERICAL variables while
- re-code every value of '-' or '&' into missing. In SPSS, the command
- is RECODE VARA (CONVERT) '-'=99 '&'=99 INTO VARB
- Is there an equavalent command in SAS?
-
- 3. I have another data set in SPSS system format. I need to 'merge'
- or 'match' this file with the subset of the SAS DATA FILE. The
- matching variable is IDC. How do I do this?
-
- Some simple examples would be very helpful.
-
-
- I'm scared and confused by the volumes of manuals of SAS. I tried many
- times to figure out the ways to solve my problems, but the explanation
- and examples are so difficult to be understood. Why don't the SAS
- people write simple manuals like the SPSS people do? Many people
- told me that SAS gives better statistical outputs. I guess I have
- to learn this no matter how painful it will be.
-
- Thank you for any help.
