How do I change the encoding of a SAS dataset?
When a file that contains character data has encoding that is different from the encoding of the SAS session, use the ENCODING= option in the FILENAME, INFILE, or FILE statement to specify the file encoding. SAS can transcode the data from its original encoding to the current SAS session encoding.
How do you use encoding in SAS?
You can specify encoding for a SAS library by using the LIBNAME statement’s INENCODING= option (for input files) and the OUTENCODING= option (for output files). If both the LIBNAME statement option and the ENCODING= data set option are specified, SAS uses the data set option.
What is wlatin1 encoding?
wlatin1 is a single-byte character set, meaning that each character could be stored in one byte. But UTF-8 is a multi-byte character set, meaning that characters need 1, 2, 3 or even 4 bytes to be stored. The special character µ, needs 2 bytes with UTF-8 encoding.
Where is the SAS configuration file?
The default configuration location is c:\program files\SASHome\SASFoundation\9.4\nls\en\sasv9. cfg. SAS requires a configuration file, so you must use a SAS configuration file regardless of whether you are using interactive or batch mode.
What is SAS configuration file?
A configuration file contains SAS system options that are set automatically when you invoke SAS. SAS uses two types of configuration files: the system configuration file, which is used by all users at your site by default. Your on-site SAS support personnel maintain the system configuration file for your site.
Where is Autoexec SAS located?
The autoexec. sas file will be located in either the current directory or in the root directory (i.e., C:\).
How do I recode data in SAS?
To recode values in a data set:
- Select the input data source.
- Specify whether you are recoding values for a numeric or character variable.
- Assign the variable whose values you want to change to the Variable to recode role.
- Specify a name for the variable that contains the recoded values.
How do you change variables in SAS?
Renaming Variables MODIFY SAS-data-set; RENAME old-name=new-name; SAS-data-set. specifies the name of the SAS data set that contains the variable that you want to rename.
What are different encoding techniques?
Encoding is the process of using various patterns of voltage or current levels to represent 1s and 0s of the digital signals on the transmission link. The common types of line encoding are Unipolar, Polar, Bipolar, and Manchester.
Which encoding is best for categorical data?
Target Encoding This type of encoding is a type of bayesian encoding method where bayesian encoders use target variables to encode the categorical value. The target encoding encoder calculates the mean of the target variable for each category and by the mean, the categories get replaced.
Where is my SAS config file?
How do I add code lines in SAS?
The SAS log often uses line numbers to reference problems in WARNINGs and ERRORs. So of course, you should have line numbers displayed in the program editor. But they aren’t on by default. Go to Program → Editor Options and select “Show line numbers” to turn them on.
How do I run an Autoexec in SAS?
Setting up a user-specific autoexec
- From the top Menu bar: Tools -> Options ->SAS Programs.
- In the Additional SAS code section, select the checkbox for Submit SAS code when server is connected.
- To the right of this checkbox, click the Edit button and enter the code to be run whenever you connect to a workspace server.
What is SAS Autoexec?
The autoexec file contains SAS statements that are executed automatically when you invoke SAS or when you start another SAS process. The autoexec file can contain any SAS statements. For example, your autoexec file can contain LIBNAME statements for SAS libraries that you access routinely in SAS sessions.
