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 .
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.
How do you transpose character variables in SAS?
- If you omit the VAR statement, then the TRANSPOSE procedure transposes all numeric variables in the input data set that are not listed in another statement.
- You must list character variables in a VAR statement if you want to transpose them.
How do I transpose row to column 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 I create a proc transpose in SAS?
proc transpose data = transp out= outdata; run; The above code creates a data set called outdata which contains values of variable ‘Marks’ stored in horizontal (wide) format. In other words, it transposes only variable i.e. Marks (which is numeric)….SAS : PROC TRANSPOSE with Examples.
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.
What is proc transpose?
Creates an output data set by restructuring the values in a SAS data set, transposing selected variables into observations. Tip: You can use data set options with the DATA= and OUT= options. For more information, see Statements with the Same Function in Multiple Procedures.
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 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 ….
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 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 a label name in SAS?
Changing a variable label in SAS is exactly the same as assigning a label. SAS doesn’t require you to specify the old label before you can define the new label. So, you can directly use the LABEL statement to modify the current label.
How do I assign a label in SAS?
First, you must create the label formats with proc format using a value statement. Next, you attach the label format to the variable with a format statement. This format statement can be used in either proc or data steps. An example of the proc format step for creating the value formats, forgnf and $makef follows.
How do you change a variable name in SAS?
How do I label a dataset?
Details. You can use the LABEL= option on input and output data sets. When you specify LABEL= on input data sets, it assigns a file label for the duration of that DATA step or PROC step. When you specify LABEL= for an output data set, the label becomes a permanent part of that file.
What is SAS label statement?
Using a LABEL statement in a DATA step permanently associates labels with variables by affecting the descriptor information of the SAS data set that contains the variables. You can associate any number of variables with labels in a single LABEL statement.
How do I change labels in SAS?
LABEL variable=<‘label’>; SAS-data-set….Assigning, Changing, or Removing Labels
- Enclose the text of the label in single or double quotation marks.
- Limit the label to no more than 256 characters, including blanks.
- To remove a label, use a blank as the text of the label, that is, variable =’ ‘ .
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 to add labels to transposed data in Proc?
The Proc Transpose option LABEL sets the value of the label for the _name_ variable. If you are using the ID option you can include another variable that holds the intended label for the transposed variable names created by use of ID. Or use Proc DATASETS to add labels to the created transposed data after the set is created.
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.
What is the _name_ variable in SAS?
By default, SAS creates a _NAME_ variable that shows which variable is used for the values in the dataset. Feel free to use the DROP statement to drop this variable when using PROC TRANSPOSE:
