Here is a solution that avoids number to character conversion and back again, and also deals with fractional and negative values. int (abs (num)/10** (log10 (abs (num))-3)) It works by dividing the number by the requisite power of 10 (including negative power) and truncating the decimal portion. Richard.If first with multiple BY variables and counts/calculations. Hi, everyone.

While Andreas already answered your question, I thought you might find it equally useful to know that the reason that you don't have to include Total_Amount_Last_Learning in a retain statement is because it is automatically retained because you used in the statement TOTAL_AMOUNT_LAST_EARNING + AMOUNT_LAST_EARNING ; . The variable on the left in such sum statements are automatically retained.ECSTDTC and LAST.ECENDTC could only be true if there is only one record for that value of ECSTDTC within that value of USUBJID.

Posted 01-31-2012 05:45 PM (814 views) | In reply to littlestone. The problem is the VAR_1 is different on every observation. So within the set of constant values for ID and VAR_1 every value of VAR_2 is unique. data want ; set test; by id var_2 notsorted; var_3 = last.var_2; run; 3 Likes.The hash OUTPUT method will overwrite a SAS data set, but not append. That can be costly. Consider voting for Add a HASH object method which would append a hash object to an existing SAS data set Would enabling PROC SORT to simultaneously output multiple datasets be useful? Then vote for ... Help with first. and last.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>.With my limited understanding of Arrays and SAS programing I thought that i could use an arrays variable name to locate data into the array. I cant seem to google anything that explains this very well. In this data step I am trying to use the Usage_type that is equal to the array variable names to change the data from long to wide.

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.

Hi All, I'm reading a list of text files, and would like a way to identify whether a record I am reading is the first record of a file or not, and whether it is the last record of a file or not.

Your data will be in a SAS data set, use the proper tool, use SAS data steps and data step functions.--The. IF LAST.PERIOD; Statement is a Subsetting If Statement. Meaning that anything below it executes only then the condition (last.period = 1) is true. Since there is an implicit output statement at the bottom of the data step, this too executes only when last.period is true. The DATA to DATA Step Macro.

Richard.Since SAS processes row by row, we create a counter to count the number of observations per group. If SAS processes the first row of a new group, the counter is set to one again. We create the counter with the RETAIN statement. The RETAIN statement “remembers” the last value of the counter when SAS starts processing a new row.FIRST and LAST processing ...

Sometimes SQL variants have different methods of implementing this type of functionality.

Example 4: Retaining the First Observation of Each BY Group. The EQUALS option, which is the default, must be in effect to ensure that the first observation for each BY group is the one that is retained by the NODUPKEY option. If the NOEQUALS option has been specified, then one observation for each BY group will still be retained by the ...In today’s competitive retail industry, it is crucial for businesses to find ways to stand out from the crowd and deliver exceptional customer experiences.

This function uses the following basic syntax: lag1_value = lag (value); By default, lag finds the previous value of some variable. However, you can use lag2, lag3, lagn, etc. to calculate the 2-lagged, 3-lagged, n-lagged, etc. values of some variable.. The following examples show how to use the lag function in ...Re: If first. then group by; how to restart count. You have to include the variables in the BY statement if you want SAS to set values for FIRST. and LAST. variables for them. You have to tell SAS not to reset the new variable COUNT to missing when it starts the next iteration.The easiest way to remove the first character from a string in SAS is to use the SUBSTR function.. You can use the following basic syntax to do so: data new_data; set original_data; string_var = substr (string_var, 2); run; . This syntax extracts the substring starting from the second character to the end of the string, which has the effect of removing the first character from the string.Re: If first. then group by; how to restart count.

In the example below we set this argument to “b” to calculate the first day of …For posterity, here is how you could do it with only a data step: In order to use first. and last., you need to use a by clause, which requires sorting: proc sort data=BU; by ID DESCENDING count; run; When using a SET statement BY ID, first.ID will be equal to 1 (TRUE) on the first instance of a given ID, 0 (FALSE) for all other records.Re: first.id and last.id. Whenever you are using the BY statement the source data need to be sorted in the same way as specified in the BY statement. Exception: when the data is stored in SPDE, SPDS or an external RDBMS the sorcerer engine sorts the data on the fly based on your BY statement.

Had ...If you came from a SAS programming background, you may have seen the INTNX function that applies basic arithmetic to dates. For example, you can use the function to add or subtract days, weeks, months, quarters, or years to an existing date.
