With regard to SAS programming and statistics, I have done a comprehensive summary, and the readers who missed them can be poked here:
SAS programming tips are easy to ignore today.
(1) Let SAS can also use Chinese variable names
The default SAS naming rule is unable to use special characters such as Chinese as a SAS name, but we can break through this restriction through the validvarname = any system option, but we can even break through the value of the data set name through the validmemname = extend system option.
OptionsvalidMemname = extend validvarname = any;
↑ Break through naming restrictions
Although this is the case, it is not recommended. In the case of indeed helpless case, if you don't give you a hundred Chinese variable CSV file, you can consider emergency.
(2) Ignore Open SAS Dataset Tips Format Error
Sometimes I will touch the SAS dataset given, after setting the logic library with libName, but still can't open, always prompt format errors, at which time this type of error can be ignored with the NOFMTERR option.
Options nofmterr;
(3) One button cleans all results from SAS
When the results of the SAS result window, I hope to clean up as soon as possible. When the foundation of a clean refreshing basis, the DM command can be used. ,
↑ Results tree directory results
DMODSRESULTS "CLEAR" Continue;
Run the above code directly, give you a refreshing world, the effect is as follows.
↑ Results tree directory results one-click cleaning
(4) SAS drawing designer to help you write pictogram code
About SAS drawing, I have written a series of tutorials, the directory is as follows:
But it is really willing to use SAS to write code to draw less. In fact, we can try% sgdesign, draw the way with drag and drop, and save the SAS GTL code behind it in the future.
% Sgdesign;
↑ SG Designer
↑ 图 图 图 g g 代
(5) Escape "black hole" error
Is there such a situation: Run any SAS code, there is no result, no error feedback, just repeatedly displays your code in the log.
This is the so-called "black hole" error, you entered such a "black hole", any running SAS code was inhaled by him, with any feedback!
What? You haven't encountered it yet, it seems that experience is not enough. Run a macro code below, try the other SAS procedure behind.
% macrotest;
% PUT this is a "balk Hole" test;
% PUT ****% STR (Gu's Wechat) ****;
% mend;
% Test
/ * The following code does not respond, no matter how it is running? * /
Proc Print Data = Sashelp.class;
Run;
How to break? Run the following code, you can jump out!
');
% mend;
In fact, this example is still relatively simple, carefully observed macro definition, and the problem may be caused by single quotes. Complete match is like this:
% PUT ****% STR (GU's WeChat) ****;% mend; ');% mend;
However, if we are in a complicated macro, we may not find the problem so much, fortunately, we can use a universal code, run multiple times, you can escape the black hole! This is:
* '; * "; *); * /;% Mend; run;
(6) SAS EG / SAS STUDIO writes
Beginners may always remember the function, can't remember the options. It doesn't matter, let SAS will give us prompts. At this time, you can try to write code in SAS EG or SAS Studio.
↑ SAS Studio
(7) One-button formatted someone else's messy code
Do you want to endure in a straight-up SAS code written by others? Don't, in SAS EG, with Ctrl + i-one, indent the code, neatly, one to create a compulsive patient.
