GPS finding and mark interesting POI within table with large GPS points collection
...#like in these vectors:
(GPSfindings$Lat =c(2.2, 2.1, 3.3 ) )
(GPSfindings$Lon =c(1 , 1.1, 4.2 ) )
(GPSfindings$time =c(2 ,10 , 12 ) )
(GPSfindings$Lab =c("A","A" , "B" ) )
(GPSfindings$POI_lat =c(2 ,2 , 3.2 ) )
(GPSfindings$POI_lon =c(1.1,1.1 , 4.1 ) )
#and as result obtain marked vector:
(GPS$Lab=c(NA,"A",NA,NA,NA,NA,NA,NA,NA,"B",NA,NA,NA,NA,NA,NA))
#1) Is that possible without using specialized package?
#2) Any specialized package function realize that?
