the ids for the xy coordinates used to calculate the distance. Here is the piece of code I'm working with: code excerpt: g long rad10=. g double dist1=. g id1="" merge using univpoints00_0 forv i=1/`np' { qui vincenty `=latitude[`i']' `=longitude[`i']' sch_lat sch_lon, hav(dis) g within10=dis<10 su within10, meanonly qui replace rad10=r(sum) in `i' su dis, meanonly qui replace dist1=r(min) in `i' qui levelsof unitid if dis==dist1[`i'], loc(vs) foreach v of loc vs { qui replace id1="`v' "+id1 in `i' } drop dis within10 } end excerpt

attached to the point the distance to which is being calculated? Thanks David Torres UMich * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
