Jan 17, 2023 · 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. LAST.variable_name assigns a value of 1 to ...

SAS automatic variable _NAME_ contains the name of the variable being transposed. 2. Transposing two variables. With only a few modifications, the above example can be used to reshape two (or more) variables. The approach here is to use proc transpose multiple times as needed. The multiple transposed data files then are merged back.

I would use the following to extract the first day of current year: (to , putn() is abundant here): %let date_range_min = %sysfunc(intnx(year,"&sysdate9"d,0, b), date9.); Doing so, you only need to call a SAS function once, and you get to use an existing macro variable that has the system initiating date (be aware of that though). or something I would cal it cheating:The next statement tells SAS when to reset the count and to what value to reset the counter. SAS has two built-in keywords that are useful in situations like these: first. and last. (pronounced "first-dot" and "last-dot"). Note that the period is part of the keyword.

SAS does not write FIRST. and LAST. variables to the output data set, so you cannot display their values with the PRINT procedure. Therefore, the simplest method of displaying the values of FIRST. and LAST. variables is to assign their values to other variables. This example assigns the value of FIRST.TOURTYPE to a variable named FirstTour and ...1:36.

It is in that sense that they are temporary. Because SAS does not write FIRST.variables and LAST.variables to output data sets, we have to do some ...While you may have obscure problems with names like Vincent Van Gogh, your basic idea for first and last name are correct. You can check whether there are 3 names, and only assign the middle name if there is one. The DATA step syntax is easy: if countw (fullname) > 2 then second = scan (fullname, 2, ' '); The SQL syntax is harder, and just a ...

This is a "must have" tool if you're going to program using SAS. first.var is created by the BY statement in the DATA step. It is automatically 1 or 0. As the data step progresses through the incoming data, whenever VAR1 takes on a new value, first.var1 is 1. Otherwise, first.var1 is 0.In the above example what I am lloking for is writing code to basically say: If your first observation for the customer is "C" and your last is also "C" then indicator = "PASS". but if your first observation of the flag is "C" and your last observation is "O" then your indicator = "FAIL". So the result should look like this.I want all of them to be 5-digits but am having trouble extracting the first 5 digits of the variable.

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.Using a BY statement allows us to determine the first and last observation in the "by-group," i.e., all the records with the same value in the variable specified in the BY statement (and often called the "by-variable"). When you use a BY statement in the DATA step, SAS creates two temporary variables that may be used only in that DATA step.

set ia.usage nobs = nobs firstobs = startobs; drop startobs; run; proc print data = last10; run; If you want both in the same proc print, you can create two views and combine them into another view, then print it: data first10 /view = first10; set ia.usage(obs = 10); run; data first10_last10 /view = first10_last10;

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;Example 1: Print Entire Dataset Observations. The fundamental of this procedure is to print observations from the SAS dataset. It can be done simply by invoking the PRINT procedure by passing the dataset name. Here is a simple example to print all the observations from work.my_cars.1:36. The US services sector unexpectedly contracted in April for the first time since 2022 as a gauge of business activity slumped to a four-year low and a measure of …Using a subsetting IF statement before testing the FIRST.ID flag could have, in theory, caused a problem as it could have removed the observation where FIRST.ID is true. But since you are removing all of the observations where ID is missing it doesn't really cause any trouble. Your data step is equivalent to these other forms: Solved: Hello ...Hello, I have a SAS query that has been giving me trouble for quite some time (I am using SAS 9.4).
