Since they are never output to the final dataset, you might consider them temporary. I prefer to think of them as automatic, like _N_ and _ERROR_, which are also available for the duration of …Hi: FIRST.byvar and LAST.byvar are automatic variables that exist for the duration of the DATA step program, but they can be used in the program.

Re: Remove Duplicates First. and Last. For the first record of AB1 , the service_date_to has 10/14 which overlaps with second record's service date from. Similarly, 2nd record has dates 10/14 to 10/18 which overlaps with 3rd record dates i.e. 10/15 and 10/16. I retain first record since it has the oldest date i.e. 10/12.

IF first.recid then firstpat = 1; RUN; When SAS encounters the first patient number, the temporary SAS variable, FIRST.RECID, is automatically set to 1. For all other records, this variable is set to 0. Those patient records are clearly identified. The same would be true for identifying the last patient number (LAST.RECID).Sometimes SQL variants have different methods of implementing this type of functionality. For doing this code conversion, indenting your code also makes it much easier to read. data hsshow(/*drop=days_span*/); set show_all; by member_i prognum mon; if first.mon then days_elig=0; days_elig + days_span; if days_elig gt days_in_mon then …

And, Why for the first set are you missing the first entry? subs1 = "JDE1, LEI0" -> where's the first one? So you're trying to create subsets for each tech group based on the subtech groups? You can add a WHERE to the select statement, but I don't understand why you don't just join them and find the values you need. or use an approach like this.first.DATE1 and last.DATE1 mark the beginning and the end of each group for DATE1 inside each group for ID. So to find the start or the end of any (ID, DATE1) group inside the dataset you should look only at FIRST and LAST for DATE1. Now to finding the max value of DATE2.Listen. 2:27.

Hi, Really annoyed with myself that I can't figure this out (or find the answer online). I have a dataset that covers the last four years (a single month end entry for each account) of accounts moving through arrears cycles and I am trying to identify the first and last occurrence of each account being at each level of arrears cycle so I can calculate …

If you have number with integer values then the last two digits is just the remainder when dividing by 100. Which 10**2. So to get the list N digits from an integer use: last2num=mod(number,10**2); last5num=mod(number,10**5); If you have a string you showed how to get the last N characters.Scenario: Want to pull only the first record of a dataset by user ID (may be duplicates for any given user) by earliest date and record ...FIRST-dot and LAST-dot processing is a topic that deserves its own tutorial, but you can learn more from this article by @Rick_SAS.

Change the BY statement to: BY PHASE NOTSORTED; That will permit your BY statement even though the data are not in order by Phase. Also note, if your actual data set is larger and might contain more than one SUB value, you may need to use:

The substring between the beginning of the string (^) and the first hyphen as well as the substring between the last hyphen and the end of the string ($) -- both are sequences of arbitrary characters except the hyphen, denoted by [^-]*-- are not part of FINAL. The replacement \1 stands for the substring matched by the pattern .* in parentheses.Hi all! I am having trouble using array, first., and last. to create only one observation and multiple variables per subject.

I have been trying first./last. processing with by statements, but I can only get that to work with one variable at a time. Is there a way to do this for N variables within the same data ... Re: Finding the first and last values. This is another example where bad data structure causes one to write unnecessarily complicated code. First, transpose your data to a long layout: ; proc transpose data=have out=long (where=(col1 ne "")); by name; var source:; run; Now the exercise becomes very simple:At the very first observation of each group (identified by the internal variable first.date, which takes the value 1 in this case), seq_id is set to 1. For all the next observations of the same date, the condition 'if first.date' is false so SAS applies the 'else' statement, which results in the accumulation of seq_id's previous value + 1 -> so ...

To convert the SAS date value to a calendar date, use any valid SAS date format, such as the DATE9. format. data _null_; x=intnx('month', '15MAY2025'd , 1); put x date9.; run; INTNX returns the value 01JUN2025. Similarly, you can find the date of the first day of the last month by passing increment value "-1".Hi all, I'm just wondering if there is a equivalent of SAS's FIRST. and LAST. variables in R?

The DO statement, the simplest form of DO-group processing, designates a group of statements to be executed as a unit, usually as a part of IF-THEN/ELSE statements. The iterative DO statement executes statements between DO and END statements repetitively based on the value of an index variable. The DO WHILE statement executes statements in a DO ...

You can use the FIRST. and LAST. functions in SAS to identify the first and last observations by group in a SAS dataset. Here is what each function does in a nutshell: FIRST.variable_name assigns a value of 1 to the first observation in a group and a value of 0 to every other observation in the group.So you will need to make a NEW variable so you can RETAIN the first value. If you don't need the original variable (the one with the zeros) then DROP it. If you would like the new variable to use the same name as the old then add a RENAME statement. data want; set have; if _n_=1 then newvar=x; retain newvar; drop x;If you want to reproduce COUNT in the datastep you will have to use the double DOW.

Second time to output all rows. data out; do _n_ = 1 by 1 until (last.date); set test ; by ID date; if first.date then count = 1;The Basics. The INDEX function searches source, from left to right, for the first occurrence of the string specified in excerpt, and returns the position in source of the string's first character. If the string is not found in source, INDEX returns a value of 0.will still be useful for SAS users using earlier versions of SAS software. This program capitalizes the first letter of the two character variables FIRST and LAST. The same technique could have other applications.

I need to transform my data set from "original" to "new" as shown in the picture. Because the "priority" variable can not be sorted, it seems that first. and last. variables would not work here, no?
