Input 'miles' +(-15) '"' distance :comma12. SAS also has a couple of in-built functions to calculate distance between two points. Everything's big in Texas - at least that's what they say Therefore let's have a bit of graphical fun, and use Texas as a unit of measure (let's call it a 'tex'). Both functions use the Vincenty distance formula. PROC EXPAND is one of the most useful procedure of SAS ETS. Prior to SAS 9.2, a data step was used to compute such distances, commonly with the Haversine formula. It has multiple functions such as creating lag, lead and moving average variables by group (s), aggregation of previous k rows etc.
* add an observation to the data set DISTANCE_TIME Otherwise time = 60*input(scan(text,1,' '),best.)

Specifically, we use the SAS Geodist function to calculate the geodetic distance in. *creating variables for the top 3 closest*/ Use geodist function to calculate straight line distance increase as a function of individual heterozygosity (Van Straalen.
