Question

What does this code do?

proc import datafile="d:/collect817/bird_count.csv"
dbms=csv out=bird817 replace;
run;

a. It creates a SAS data set named bird817 in the work library from the CSV file bird_count and replaces bird817 whenever the CSV file is updated.
b. It creates a SAS data set named bird817 in the work library from the CSV file bird_count.
c. It uses the CSV engine to directly read the data file bird_count.csv,

Answer 1

The SAS code imports data from a CSV file named bird_count.csv into a SAS data set named bird817 in the Work library, replacing any existing bird817 data set.

Step-by-step explanation:

The code snippet provided is a SAS (Statistical Analysis System) program statement that performs a data import operation. Specifically, the PROC IMPORT statement is used to create a SAS data set from an external data file, in this case, a CSV (Comma-Separated Values) file.

The datafile="d:/collect817/bird_count.csv" specifies the location and name of the CSV file to be imported. The dbms=csv indicates that the data file is in CSV format.

The out=bird817 option specifies the name of the SAS data set to be created (bird817), and it will be placed in the Work library by default. Lastly, the replace option allows the bird817 data set to be overwritten if it already exists.

The correct interpretation of this code snippet is: It creates a SAS data set named bird817 in the work library from the CSV file named bird_count and replaces it if bird817 already exists whenever the code is run (not whenever the CSV file is updated).
