|Working with SAS Data Sets|
You can create a SAS data set from a matrix by using the CREATE statement with the FROM option. This form of the CREATE statement is as follows:
Suppose you want to create a SAS data set named RATIO containing a variable with the height-to-weight ratios for each student. You first create a matrix containing the ratios from the matrices HEIGHT and WEIGHT that you have already defined. Next, use the CREATE and APPEND statements to open a new SAS data set called RATIO and append the observations, naming the data set variable HTWT instead of COL1.
htwt=height/weight; create ratio from htwt[colname='htwt']; append from htwt;
Now submit the SHOW DATASETS and SHOW CONTENTS statements:
> show datasets; LIBNAME MEMNAME OPEN MODE STATUS ------- ------- --------- ------ WORK .CLASS Update WORK .RATIO Update Current Input Current Output > show contents; VAR NAME TYPE SIZE HTWT NUM 8 Number of Variables: 1 Number of Observations: 18 > close ratio;As you can see, the new SAS data set RATIO has been created. It has 18 observations and 1 variable (recall that you deleted 1 observation earlier).
