First last in sas.

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.data step1; set have; date=datepart(datetime); time=timepart(datetime); format date yymmdd10. time tod5.; run; Now sort by subject date and time and then take the last one for that date. proc sort data=step1 out=want; by subject date time; run; data want; set step1; by subject date time; if last.date; run;SAS matches the first value in the list with the first variable in the list of elements, the second value with the second variable, and so on. Element values are enclosed in quotation marks. To specify one or more initial values directly, use the following format: (initial-value(s) ... SAS uses the last value.) You can also use RETAIN to assign ...The first two functions that actually remove blanks in SAS are the TRIM-function and the TRIMN-function. Both functions remove trailing blanks. However, they differ in how they deal with strings of multiple blanks. If a string consists of only blanks, the TRIM-function returns one blank, while the TRIMN-function returns zero blank characters.By default, SAS will use not just one but all of the delimiters in the default list. This can become problematic in certain cases when your data contains multiple delimiters. In the SASHELP.BASEBALL dataset, the NAME variable contains a list of first, last and middle names. The structure is as follows: <last name>,<firstname><blank><middlename>.

I have a dataset as follows: data have; input ID ID1 Mark1; datalines; 1 1 . 1 1 76 1 1 67 2 2 . 2 2 32 2 2 45 run; I would like to group by ID and ID1 and extract the first and last non-missing values of mark for each group so that the resultant dat...You can use 9 and get strings like in your data lines. Or 11 and get hyphens. (or 7 and not be able to tell what century the dates are in). data want; set have; by Section ID; if first.ID then First_day=date; retain first_day ; if last.ID ; Last_day=date; format first_day last_day date9.; drop date; run;TITLEn will replace the Nth title line and remove any titles after that. So either of these statements should clear the titles. TITLE1; TITLE; Note that TITLE statements issued in the middle of a step will take effect when that step produces output. So make sure to terminate your PROC steps with the appropriate statement for that PROC (RUN or ...

middle=scan(name,2,'09'x,'m'); last=scan(name,3,'09'x,'m'); run; Check if your data is delimited by tab or someway to identify the first, middle and last name. As far as I know all the source systems will create the string with proper delimiters to identify. If not you may need to change the way your source data is sent.

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 …Re: Finding first (or last) record using SQL. You could use the SQL to do ORDER BY before using the data step for First or Last processing.

Re: counting with first last. Posted 06-05-2013 03:55 PM (1500 views) | In reply to SAS_new. Yes, it can be done with .last variables. I assumed the data has the structure you presented : data visits; length patient visit $10; infile datalines missover; input patient visit @; do while (not missing (visit));2. You want to SORT the data by SUBJECT and NO. But tell the DATA step to group it by SUBJECT and AVAL. You will need the NOTSORTED keyword because it is not sorted by AVAL value. set test; by SUBJID AVAL notsorted; if first.AVAL then FLG = 1; if last.AVAL then FLG = 2; PS The FIRST. and LAST. flag variables are not functions.4. Using Joe's example of a macro variable to specify the number of observations you want, here is another answer: do _i_=nobs-(&obswant-1) to nobs; set have point=_i_ nobs=nobs; output; end; stop; /* Needed to stop data step */. This should perform better since it only reads the specific observations you want.The technique you are using is better for test if a string is a number, so strings like 1e4 would be read correctly. If your numbers could include commas or dollar sign use COMMA informat. If you are trying to see if string is a SAS name NVALID function. [pre] data _null_; input string $16.; x = anydigit (string);The second "T" in "CATT" stands for Trim. The TRIM function in SAS trims the trailing blanks from variables. If you want to know more about the TRIM function and other functions that remove blanks, I recommend this article. Method 4: The CATS Function. The fourth method to combine multiple strings in SAS is the CATS function.How it works. FIRST.variable = 1 when an observation is the first observation in each group values of variable ID. FIRST.variable = 0 when an observation is not the first observation in each group values of variable ID. LAST.variable = 1 when an observation is the last observation in each group values of variable ID.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 ...

If you use a by statement along with a set statement in a data step then SAS creates two automatic variables, FIRST.variable and LAST.variable, where variable is the name of the by variable. FIRST.variable has a value 1 for the first observation in the by group and 0 for all other observations in the by group.I have a dataset that has variables ID, Date, and Value. For each ID that has more than one Value, I want to output the earliest observation into a new column 'First', and the latest observation into a new column 'Last'. For IDs that only have one Value, I want the observation to be ignored. The final aim is to do a scatter plot of 'First' vs ...CDC examined emergency department (ED) visits associated with heat-related illness (HRI) from the National Syndromic Surveillance Program and compared …The SQL language as originally defined in the 1980's and codified into 1992 standard that PROC SQL supports has no concept of first and last.

FIRST.variable = 1 when an observation is the first observation in each group values of variable ID.

The SAS data step function SUBSTR (commonly pronounced "sub-string") function is used to work with a specific position or positions of characters within a defined character variable. The function focuses on a portion of a string and can go on either side of the "=" sign in a data step statement.

It will not delete all duplicates. This will delete only the last record of each CPNP group if it is not first and also where plant=USM.

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). east prairie obituaries Here's an example of how that would work. Some efficiency tricks: Use format dtdate9 on your datetime variable to summarize data by date. Use Range for the date variable to obtain the max time - min time. Datetime is stored as seconds, so convert to a number by dividing by 60 for minutes and another 60 for hours.In this example, PROC SORT creates an output data set that contains only the first observation of each BY group. The NODUPKEY option prevents an observation from being written to the output data set when its BY value is identical to the BY value of the last observation written to the output data set.Then using first. and last. variables and 2 cumulative (summarized) variables, you can generate this #1 report using the data set created in the DATA step program. I also included 2 separate steps for PROC REPORT and PROC TABULATE that generate the numbers you want without using a DATA step program:
