How Do I Transpose A SAS Dataset?

How do I rename a column in Proc transpose?

Instead of using the RENAME= data set option to rename the _LABEL_ variable, you can also use the LABEL= option from the PROC TRANSPOSE statement to rename the _LABEL_ variable..

How do I convert character to numeric in SAS?

To convert character values to numeric values, use the INPUT function. new_variable = input(original_variable, informat.); The informat tells SAS how to interpret the data in the original character variable.

How do you remove duplicates in SAS PROC SQL?

Two approaches to removing duplicates will be illustrated, both using the DISTINCT keyword in a SELECT clause. Using PROC SQL and the DISTINCT keyword provides SAS users with an effective way to remove duplicate rows where all the columns contain identical values.

How do you transpose multiple variables in SAS?

If only one variable needs to be transposed, PROC TRANSPOSE can perform this task directly. If however two or more variables need to be transposed, you need to transpose each variable separately and then merge the transposed data sets, which can be time consuming.

How do I change data type in SAS?

SAS uses the BESTw. format, where w is the width of the character variable and has a maximum value of 32. You cannot change the type of a variable. You will need to create a new variable from the old variable with the new data type and then drop and rename to keep the original names.

What is the definition of ID statement when using PROC transpose?

Specifies one or more variables in the input data set whose nonmissing formatted values name the transposed variables in the output data set. If the value of any ID variable is missing, then PROC TRANSPOSE writes a warning message to the log. …

How do I rename a variable in SAS?

There may be occasions in which you want to change some of the variable names in your SAS data set. To do so, you’ll want to use the RENAME= option. As its name suggests, the RENAME= option allows you to change the variable names within a SAS data set. RENAME = (old1=new1 old2=new2 ….

Do loop SAS data step?

Iterative DO loops are the simplest form of DO loops that can be executed within a SAS Data Step. The actions of an iterative DO loop are unconditional, meaning that if you define a loop to execute 50 times, it will execute 50 times without stopping (unless an error occurs during processing).

What does Proc Summary do in SAS?

When we specify NWAY, Proc Summary limits the output statistics to the observations with the highest _TYPE_ value. This means, that SAS outputs only the observations where all class variables (if any) contribute to the statistic. Consequently, no overall statistics appear in the output.

What does Proc transpose do in SAS?

VAR -[Transpose Column] It lists the actual data that needs to be transposed. If you do not include a VAR statement, the procedure will transpose all numeric variables that are not included in a BY statement or a ID statement. If youwant to transpose a character variable, a VAR statement is required.

How do I set variable length in SAS?

Specifying a New Variable in a LENGTH Statement The maximum length of any character variable in the SAS System is 32,767 bytes. For numeric variables, you can change the length of the variable by using a subsequent LENGTH statement.

What does Proc format do in SAS?

PROC FORMAT is a procedure that creates map- pings of data values into data labels. The user de- fined FORMAT mapping is independent of a SAS DATASET and variables and must be explicitly as- signed in a subsequent DATASTEP and/or PROC. PROC FORMAT will not allow 1-to-many or many- to-many mappings.

How do you transpose character variables in SAS?

In order to transpose both numeric and character, you must list all variables to be transposed on the VAR statement. Mixed data values of character and numeric that will occupy the same column must be of the same data type in accordance with SAS data rules. All numeric values are converted to character.

What are the data types in SAS?

SAS has only two data types: real numbers and fixed length character strings. Dates and times are internally stored as numbers. Macro variables are always characters.

What does transposing data do?

Transposing data is where the data in the rows are turned into columns, and the data in the columns is turned into rows. Our first example will result in a static solution (meaning the transposed data will not update if the original data changes). The second and third examples will be dynamic.

How do I merge in SAS?

To merge two or more data sets in SAS, you must first sort both data sets by a shared variable upon which the merging will be based, and then use the MERGE statement in your DATA statement.
