问题 Hi I was trying to create a macro that only contains macro variable creation but it failed. Here is an example: %macro createvariable; %let a = 5; %let b = 6; %mend createvariable; %createvariable; data test; c = &a + &b; run; But it will work as: %macro createvariable; %let a = 5; %let b = 6; data test; c = &a + &b; run; %mend createvariable; %createvariable; So I was wondering if SAS won't be able to create a macro with only macro variables creation in it? Or there is a way to solve this

问题 I'm trying to send out ID's of a SAS dataset in an email but not able to get the format right. I just need plain text as html is getting stuck and slow. Thanks in advance to help! Any one solution would be good. I have one ID column. The first solution one gives a complete list like %include "/saswrk/go/scripts/envsetup.sas"; filename mymail email "&emaillist." subject=" &env. Records Transferred on %sysfunc(date(),yymmdd10.)"; data null; set WORKGO.recds_processed; file mymail; put (_all_)(=

问题 I'm using a Proc Summary, as I want to utilise a multilabel format. I've been going round and round trying to apply a format to my summarised outputs, but can't see how to get this without incurring warnings. Proc Summary Data = Source CompleteTypes Missing NoPrint NWay; Class Brand / MLF; Var Id Total; Output Out = Results N(ID) = Volume Sum(Total) = Grand_Total; Run; I want to format my Volume as Comma23. and the Grand_Total as Comma23.2. If I put a format statement after the outputs it

问题 I have a very basic question in SAS. for example, if the dataset called 'a', how can I put 'a' as a new column into this dataset? Thank you very much 回答1: Basically you can't. You can make a new dataset. data new; set old; dsname='NEW'; run; You can use the INDSNAME option on the SET statement to tell you which dataset you are reading data from. data new ; length indsname dsname $41 ; set old indsname=indsname ; dsname = indsname ; run; Makes more sense when the SET statement has more than

问题 Trying to do a classic hierarchy tree in SQL, using SAS (which does not support WITH RECURSIVE, so far as I know). Here's simplified data structure in existing table: |USER_ID|SUPERVISOR_ID| So, to build a hierarchy, you just recursively join it x number of times to get data you are looking for, where SUPERVISOR_ID = USER_ID . In my company, it is 16 levels. This issue comes when trying to get a branch to terminate for each user. For example, let's consider User A at level 1 has Users B,C,D,

问题 I need to obtain the sum of all the values in a column ("var1" in the code below). As far as I could determine, this is done as follows: proc means data = somedata sum var1; output out = sumtable sum = sum; run; The sum I want to use as a variable in the next step. Is it possible to have the OUTPUT statement above store the sum in a new variable instead of writing it to a whole new dataset? If so, what is the syntax for this? 回答1: In a word, no. You could store the value as a text string into

问题 This question already has answers here : An efficient way to Copying values in subsequent records - SAS (3 answers) Closed 4 years ago . Should be an easy question. I have a dataset like this: id mtna 1 . 2 . 3 1.7 4 . 5 . 6 5.2 7 9.6 8 . 9 . 10 . And I want something like this: id mtna 1 . 2 . 3 1.7 4 1.7 5 1.7 6 5.2 7 9.6 8 9.6 9 9.6 10 9.6 Basically just retain the pervious observation when there is a missing value. So I try something like this: data check; set check; retain lag_mtna; lag

问题 Hey guys thank you so much, in advance, for your help! I have a data step before the code below called "simulation_tracking3", that outputs something like: CDFx Allowed_Claims .06 120 .12 13 .15 1400 My hash table averages the Allowed_Claims based on a randomly generated value (from 0 to 1). For example, let's call this Process A, if Px = rand('Uniform',0,1) yields .09, I want it to average between the Allowed_Claims values where Px = .06 and Px = 0.12, which is (120+13)/2 The role of the

问题 This is an extension from this question In Base SAS, how can I auto refresh the explorer? RawFocus gives me a way of opening a file but it doesn't work for me as I'm using rsubmit. The updated code initially didn't work, but now it opens the wrong file. v3 rather v7. As per this pic. The code I've used for the hotkey is as follows; dm 'keydef F4 "submit ''rsubmit; %nrstr(%sysrput lastDS=&syslast;) endrsubmit;''; vt rwork.%scan(&lastDS,2,.)"'; Any questions, please let me know, J 回答1: Had to
