Example 41.9 Using the SOURCE Option to Subset Time Series from a Haver Database

You can use the SOURCE= or DROPSOURCE= option to select specific variables that belong to a certain source, similar to the way you use the KEEP= or DROP= option.

libname lib1 sasehavr "%sysget(HAVER_DATA)" 
        freq=daily 
        start=20041101 
        end=20041223 
        source="FRB";

data hwoutd;
   set lib1.haverd;
run;

title1 'Haver Analytics Database, Frequency=daily, infile=haverd.dat';
title2 '   Define a range inside the data range for OUT= dataset';          
title3 '   Using the START=20041101 END=20041223 LIBNAME options.';          
title4 '   Subset further: Using source="FRB" LIBNAME option';              
proc print data=hwoutd;
run;

Output 41.9.1 shows two series that are selected by using SOURCE="FRB" in the LIBNAME statement.

Output 41.9.1 Using the SOURCE Option and Defining a Range Using START=20041101 and END=20041223
Haver Analytics Database, Frequency=daily, infile=haverd.dat
Define a range inside the data range for OUT= dataset
Using the START=20041101 END=20041223 LIBNAME options.
Subset further: Using source="FRB" LIBNAME option
