我有Google地图和带有文本标签的坐标列表。预览时，标签重叠，因此变得不可读：

library(ggmap)
WPmap <- qmap(c(lon=4.80324, lat=52.40738), zoom = 12,  source = "google")

表kaart_rtw：

              Naam      lat     lon
1 Nieuw-Zeelandweg 52.40466 4.80214
2      Portsmuiden 52.39014 4.78554
3     Westhavenweg 52.41602 4.82282
4     Westhavenweg 52.41702 4.82282
5     Westhavenweg 52.41802 4.82282
6         Deccaweg 52.40196 4.83910
7     Coenhavenweg 52.40364 4.86195 

AmsterdamMap + geom_text(data = kaart_rtw, aes(label = kaart_rtw$Naam, x = X, y = Y)) 

有没有办法停止重叠？
