Invalid argument to input

Patelbb — Mon, 04 Mar 2019 19:07:15 GMT

Hi,

I was wondering if anyone could help me. My input statements don't seem to work for me for some reason. Can anyone see why and explain to me what I did wrong please? Thank you!

494 data dsmerged;
495     merge dstran (in=inds)
496           suppds (in=insup);
497     by usubjid;
498
499     length qval $200 icdate compdate relday 8.;
500     label qval = "Reason for disposition event"
501           icdate = "Informed Consent Date"
502           compdate = "Completion Date"
503           relday = "Number of Days on Study";
504
505     rename qval = dsreas;
506     format icdate compdate date9.;
507
508     ** Create the numeric variables for 2 new variables as indicated in the HW file;
509
510     icdate = input(INFORMED_CONSENT_OBTAINED, ?? date9.);
511     compdate = input(COMPLETED_STUDY, ?? date9.);
512
513
514     ** Create the RELDAY variable as indicated in the HW file;
515
516     relday = compdate-icdate + 1;
517
518 run;

Your input-statements generate missing values, calculations with missing-values always result in missing values. What do you expect as value for relday if compdate and/or icdate is missing?

if nmiss(compdate, icdate) = 0 then do;
  elday = compdate-icdate + 1;
end;
else do;
  elday = .;
end;

You will need to inspect your data. (Obviously, we can't help with that.)

These are the suspect variables:

INFORMED_CONSENT_OBTAINED

COMPLETED_STUDY

The programming statements expect these to be character, in the date9 format, something like: 04Mar2019

Somehow, the actual data doesn't match the expected values. So the first step is to find out what is actually in these variables.

****************** EDITED:

So you are playing around with these:

date9.

mmddyy10.

without really understanding what they mean.

First, run a PROC CONTENTS to determine whether the two key variables are character or numeric. Assuming they are character, their format in the log messages corresponds to:

yymmdd10.

I played around with the code a little more and this is what I have now but I'm still getting the same message.

The problem is NOT the input-function, but the calculation using the variables set by the input-functions.

You're simply using the wrong informat. Your character dates are in YMD order, so you have to use the proper YYMMDD10. informat.
