J'ai le problème suivant. Je veux sous-ensemble des données de data.frame A par les coordonnées dans la matrice B. La correspondance doit être entre les coordonnées deux à deux de data.frame A et de la matrice B, par exemple:Données de sous-ensemble par une condition paire (coordonnées) donnée par une autre matrice
lon lat
315 10.47 52.26
342 10.47 52.37
314 10.36 52.26
341 10.36 52.37
316 10.58 52.26
288 10.47 52.15
343 10.58 52.37
287 10.36 52.15
369 10.47 52.48
Ce sont les coordonnées, je veux utiliser pour sélectionner les lignes, qui ont les mêmes coordonnées comme dans data.frame A.
Sous-ensemble de data.frame A:
