How do you transpose in SAS?
The general format of PROC TRANSPOSE is: PROC TRANSPOSE DATA=Dataset-name OUT=New-dataset-name; BY variable(s); COPY variable(s); ID variable; VAR variable(s); RUN; In the SAS code above: The PROC TRANSPOSE statement tells SAS to execute the transpose procedure on an existing dataset called Dataset-name .
What is PREFIX in SAS?
PREFIX= prefix specifies a prefix to use in constructing names for transposed variables in the output data set. For example, if PREFIX=VAR, then the names of the variables are VAR1, VAR2, …,VARn. Interaction.
How do you transpose rows to columns in SAS?
To transpose columns:
- Open a table.
- Select Transpose in the transforms list.
- On the ID Columns tab, specify the columns that contain the row values that you want to transform into columns.
- (Optional) On the Transpose Columns tab, specify the columns that contain the data with which you want to populate the output table.
How do you transpose two variables in SAS?
How it works :
- First step, it is required to sort the variables ‘ID’ ‘time’ before using them in BY statement in PROC TRANSPOSE.
- In the first transpose of the above code, we are telling SAS to store information of all the variables in a single variable and the respective values in the another variable.
How do you use the prefix in Proc transpose?
The PREFIX= option is used to place a prefix in the transposed variable names. For example, since PREFIX = score_ is used in the PROC TRANSPOSE statement, the names of the transposed variables will be SCORE_1 and SCORE_2. You can also use the SUFFIX= option to attach a suffix in the transposed variable name.
What is ID in 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.
How do you order columns in Proc transpose?
Proc transpose creates the columns as it sees new values of the ID variable. So by putting at least one example of every possible date in the first BY group (and in the right order) then it creates the columns in the right order. Then the WHERE= dataset option deletes the extra group from the output.
How do you add a PREFIX in Proc transpose?
How do I transpose data in SAS EG?
Allow SAS Enterprise Guide to easily write the majority of the code by using the Transpose task. In the lower workspace area where the CMHPIFIXED data set is open, select Data►Transpose to start the Transpose task from the context- sensitive toolbar.
How do you add a prefix in Proc transpose?
How do I rearrange columns in SAS?
So, how do you reorder variables in a SAS dataset? You change the position of a variable in a SAS dataset with a DATA Step and the RETAIN statement. The RETAIN statement must be placed before the SET statement and is followed by the column names in the desired order.
How do I change the order of variables in a SAS dataset?
You can control the order in which variables are displayed in SAS output by using the ATTRIB statement. Use the ATTRIB statement prior to the SET, MERGE, or UPDATE statement in order for you to reorder the variables. Variables not listed in the ATTRIB statement retain their original position.
How do you reorder variables?
How to Reorder Variables in SAS (With Examples)
- Method 1: Reorder All Variables data new_data; retain var4 var5 var1 var3 var2; set original_data; run;
- Method 2: Move One Variable to Front data new_data; retain var4; set original_data; run;
- Method 3: Move Several Variables to Front.
How do I reorder column names in SAS?
- Step 1: Sort the column names by ascending order. This done in roundabout way using proc contents and proc sort and the column is sorted by its name as shown below.
- Step 1: Sort the column names by descending order.
- Step 2 : Retain that descending order there by reordering in descending order.
How do I change the order of columns in a SAS dataset?
How do you rearrange the order of variables in SAS?
You can control the order in which variables are displayed in SAS output by using the LENGTH statement. Use the LENGTH statement prior to the SET, MERGE, or UPDATE statement in order for you to reorder the variables. Variables not listed in the LENGTH statement retain their original position.
What is Proc transpose in SAS?
PROC TRANSPOSE Statement. names the SAS data set to transpose. specifies a delimiter to use in constructing names for transposed variables in the output data set. If specified, the delimiter will be inserted between variable values if more than one variable has been specified on the ID statement.
How do you print a transposed variable in SAS?
To print the output data set from the PROC TRANSPOSE step, use PROC PRINT, PROC REPORT, or another SAS reporting tool. To create transposed variable, the procedure transposes the values of an observation in the input data set into values of a variable in the output data set.
What is the purpose of the variable name in Proc transpose?
specifies a name for the variable in the output data set that contains the label of the variable that is being transposed to create the current observation. allows duplicate values of an ID variable. PROC TRANSPOSE transposes the observation that contains the last occurrence of a particular ID value within the data set or BY group.
How to use prefix in PROC step?
Prefix option goes into the PROC statement. This example will PREFIX the name of the variable with ABC before the value of the ID variable. proc transpose data=sashelp.class (obs=5) out =trans prefix=ABC; by name; var age; id sex; run;
