Note: Variable GandBd1 is uninitialized.

Perrine — Thu, 11 May 2017 15:28:44 GMT

Hi,

I am getting that note for this variable and not for the rest of the variables even if I do a proc content this variable is listed (see attached).

I tried to change the name, the values and I keep on getting that note and cannot do anything with this variable.

Does anybody know why?

Thank you for your help.

What this note is telling you is that you have created a variable called gandbd1, however you have not in the datastep, assigned a value to any row.

That is what I do not understand because there are values. See the attached screenshot.

Thanks,

And are they assigned in the same datastep as the variable is defined? That is what the note is telling you. For instance, I can get the same note with:

data want;
  length b $10;
run;

I create a variable called b, but in that dataste I assign no values to it.

Here is my code:

data missingdata;
set surv.HPLanalysis_xlsx;
if recall=3 then meantotveg=MEAN(Totvegd1,Totvegd1);
else if recall=2 then meantotveg=MEAN(Totvegd1);
if recall=3 then meantotGandB=MEAN(GandBd1,GandBd2);
else if recall=2 then meantotGandB=MEAN(GandBd1);
if recall=3 then meantotfruit=MEAN(Totfruitd1,Totfruitd2);
else if recall=2 then meantotfruit=MEAN(Totfruitd1);
run;

It works for the other variables but just not for GandBd1 and GandBd2.

They are all from an excel that has similar variables in it.

Thanks

Post the code and log. Without that, we can only make guesses.

Yes, that doesn't help me. Please post the dataset: set surv.HPLanalysis_xlsx;, as a datastep (just a few rows is fine) as text here. You can follow this post:

https://communities.sas.com/t5/forums/replypage/board-id/sas_studio/message-id/2483

Also please , post the log of the part where this occurs, does the note follow this specific datastep, if so then the two given variables are not in that dataset and are getting create in this datastep, as as they are used in a condition never get assigned a value e.g to replicate:

data have;
  Totvegd1=12; output;
  Totvegd2=1; output;
run;
/* Note above does not contain gbandbd1 */
data want;
  set have;
  result1=mean(totvegd1,totvegd2);
  result2=mean(gbandbd1,totvegd1);
run;

Do a proc contents on surv.HPLanalysis_xlsx.

The screenshot of the proc content is in my first post.

Re: Note: Variable GandBd1 is uninitialized.

RW9 — Thu, 11 May 2017 16:18:03 GMT

Ok, so:

NOTE: Variable GandBd1 is uninitialized.

NOTE: Variable GandBd2 is uninitialized

These do not exist in surv.HPLanalysis_xlsx;

At the time this dataset runs. A picture of the contents after the event does not help, as after this note the variables do exist. Run your code up to this step, don't run this step, stop before it. Now check the contents of surv.HPLanalysis_xlsx;, you will see these variables do not exist.

And WHICH data set did you run that on? Missingdata or surv.HPLanalysis_xlsx? Yes the variables would be present in Missingdata as you just created them by referencing the variable name. The calculated values are missing because they use variables that are not in surv.HPLanalysis_xlsx.

Run Proc contents on surv.HPLanalysis_xlsx and show the complete result.

The proc content is with surv.HPLanalysis_xlsx.

So finally I found it when I did a proc contents with missingdata. There was a space in my column in excel before GandBd1....

Thank you for all your answers!
