Creation of a 'ratings' dataset

The script uses a DATA STEP to define the structure of the 'ratings' dataset with 'stars' (numeric) and 'rating' (character) variables. The data is then inserted directly into the dataset via the DATALINES statement, using commas as delimiters (DSD - Delimited, Separated, Data).

Data Analysis

Type : CREATION_INTERNE

Data is created directly within the SAS script using the DATALINES statement. It does not come from an external source or from default SAS libraries like SASHELP.

DATA STEP Data

Explanation :
This code block uses a DATA STEP to create a temporary SAS dataset named 'ratings'. The 'length' statement defines the types and lengths of the 'stars' (8-byte numeric) and 'rating' (15-character) variables. 'infile datalines dsd;' indicates that the raw data is provided within the script itself (datalines) and that the delimiter is a comma, also handling quotes. 'input stars rating;' associates the read data with the variables. The lines following 'datalines;' are the inserted observations.
