Sub count required as per the below data

[Mastanvali]

Hi Team,

I have the data like below:

Subject	FolderName	FolderSeq	VSTEMP	VSTPT	count
101	Screening	1.0	37.1	Supine	1
101	Day 1	2.0	36.9	Supine	1
101	Day 8	5.0	36.8	Supine	1
101	Day 15	6.0	37.1	Supine	1
101	Day 22	7.0	36.7	Supine	1
101	Day 29	8.0	36.9	Supine	1
101	Day 36	9.0	36.9	Supine	2
101	Day 43 / ET	10.0	36.8	Supine	1
101	Safety Follow-Up	12.0	36.6	Supine	1
102	Screening	1.0	36.8	Supine	1
102	Day 1	2.0	36.8	Supine	2

102	Day 43 / ET	10.0	37.0	Supine	2
102	Safety Follow-Up	12.0	36.9	Supine	1

I am want like below, i tried m in data step but its not working.

Please post the data as data steps using datalines and describe the rules that want applied. If you have tried something, post the code you have, so that we can suggest corrections.

Hi,

I did the below logic:
proc sort data=d; by subject FolderSeq VSTEMP; run;

data d1;
set d;
by subject folderseq VSTEMP;
retain count;
if first.VSTEMP and first.subject then count=1;
if VSTEMP=lag(VSTEMP) and subject=lag(subject) then count=count+1;
else count=1;
run;
proc sort data=base2; by subject folderseq VSTEMP; run;

got the output like:

I did the below logic:

proc sort data=d; by subject FolderSeq VSTEMP; run;

data d1;
set d;

 else count=1; 
run;
proc sort data=base2; by subject folderseq VSTEMP; run;

got the output like:

While implementing the above logic only I tried to achieve the below sub_cnt and also, i want data like in sub_cnt column.

[PaigeMiller]

What is the logic here? Why is the value of sub_cnt equal to 2 for Day 29 subject 101?

[Mastanvali]

we need to flag as yes for 3 or more consecutive values. but in my logic if i have 2 consecutive values also it is flagging yes but i do not want flag as yes if i have only 2 consecutives.

I don't know what this means. 3 or more consecutive values of what? Flag for what reason? No flag is mentioned or shown in your original post.

How does the value of sub_cnt equal to 2 for Day 29 subject 101? Please walk me through this step-by-step.
