I have a global variable called "switch", which by default is set to 'N'; If a certain condition occurs then I'd like switch be = 'Y'. The code I'm using always changes switch to 'Y', regardless of the condition. That's not right. Here's my code: data _NULL_; %let switch = N; if rand('UNIFORM') > 0.3 then do; %let switch = 'Y'; end; %put &switch; run; Any ideas? Thanks! ... View more

I have the following data set resp: PatientID  RespRate1  RespRate2 ....  RespRate20 XYZ           16                18                       17 ACW          21                17                       21   For each row (PatientID) I want to be able to obtain the min, max, mean, and std of the first 10 respiratory rates, then the next ten respiratory rates. I wanted to do this:   data resp; set resp;     min1 = min(of RespRate1-RespRate10);    max1 = min(of RespRate1-RespRate10);   mean1 = min(of RespRate1-RespRate10);   std1 = min(of RespRate1-RespRate10);    min2 = min(of RespRate11-RespRate12);    max2 = min(of RespRate11-RespRate20);   mean2 = min(of RespRate11-RespRate20);   std2 = min(of RespRate11-RespRate20); run;         Yet the min, max, mean, and std functions don't work unless you list out all of the variables, i.e. min1 = min(RespRate1, RespRate2, RespRate3.... RespRate10).   Any ideas on how to do this in Base SAS (I dont want to go over to IML in this instance). ... View more

I'm trying to call R functions from within IML. To make sure SAS was set up properly, I ran PROC OPTIONS option=RLANG; The result I got indicated that the NORLANG option had been initiated. So, I tried looking for the SASV9.fcg file. But I wasn't able to locate a file with that exact name, even when searching in the SASHome directory and subdirectories. Does anyone have a suggestion on what to do? Thanks! Andrew ... View more

I'm running a regression procedure 30,000 times. By using the following I've been able to suppress all logs, listing, & HTML:    ods html close ; ods listing close; options nosource nonotes; Here's the regression equation code:   proc reg data = hr_reg ; model hr = timepoint; title "Regression of hr on time"; ods output ParameterEstimates=beta FitStatistics = rsquare; run; quit;     Even though the output is suppressed, the Results window continues to accumulate "beta" & "rsquare" SAS data sets. Is there any way to prevent that from occurring? Thanks! Andrew ... View more

The default PDF output style in Studio is not very appealing. To change it, I went to Preferences, then used the drop-down box for PDF output styles. The problem is that there are > 50 styles! Does anyone know where I can find a sample of each of those styles? Thanks! ... View more
