The SASEHAVR Interface Engine

Example 41.1 Examining the Contents of a Haver Database

To see which time series are in your Haver database, use the CONTENTS procedure with the SASEHAVR LIBNAME statement to read the contents.

libname lib1 sasehavr "%sysget(HAVER_DATA)" 
        freq=yearly start=19920101 
        end=20041231 
        force=freq;
        
data hwouty;
   set lib1.haverw;
run;
title1 'Haver Analytics Database, HAVERW.DAT';
title2 'PROC CONTENTS for Time Series converted to yearly frequency';
proc contents data=hwouty;
run;

All time series in the Haver haverw database are listed alphabetically in Output 41.1.1.

Output 41.1.1 Examining the Contents of Haver Analytics Database, haverw.dat

Haver Analytics Database, HAVERW.DAT

PROC CONTENTS for Time Series converted to yearly frequency

The CONTENTS Procedure

Alphabetic List of Variables and Attributes
#	Variable	Type	Len	Format	Label
1	DATE	Num	8	YEAR4.	Date of Observation
2	FA	Num	8		Total Assets: All Commercial Banks (SA, Bil.$)
3	FCM1M	Num	8		1-Month Treasury Bill Market Bid Yield at Constant Maturity (%)
4	FM1	Num	8		Money Stock: M1 (SA, Bil.$)
5	FTA1MA	Num	8		Treasury 4-Week Bill: Total Amount Accepted (Bil$)
6	FTB3	Num	8		3-Month Treasury Bills, Auction (% p.a.)
7	LICN	Num	8		Unemployment Insurance: Initial Claims, State Programs (NSA, Thous)

You could also use the following SAS statements to create a SAS data set named hwouty and to print its contents.

libname lib1 sasehavr "%sysget(HAVER_DATA)" 
       freq=yearly 
       start=19920101 
       end=20041231 
       force=freq;
       
data hwouty;
   set lib1.haverw;
run;

title1 'Haver Analytics Database, Frequency=yearly, infile=haverw.dat';
title2 'Define a range inside the data range for OUT= dataset,';        
title3 'Using the START=19920101 END=20041231 LIBNAME options.';
  
proc print data=hwouty;
run;

The preceding LIBNAME LIB1 statement specifies that all time series in the haverw database be converted to a yearly frequency but to select only the range of data from January 1, 1992, to December 31, 2004. The resulting SAS data set hwouty is shown in Output 41.1.2.

Output 41.1.2 Defining a Range inside the Data Range for Yearly Time Series

Haver Analytics Database, Frequency=yearly, infile=haverw.dat

Define a range inside the data range for OUT= dataset,

Using the START=19920101 END=20041231 LIBNAME options.
