我认为这是您要找的内容:
我想这就是您所寻找的:
lat = c(40.702147,40.718217,40.711614);
lon = c(-74.012318,-74.015794,-73.998284);
center = c(mean(lat), mean(lon));
zoom <- min(MaxZoom(range(lat), range(lon)));
Map <- GetMap(center=center, zoom=zoom,markers = paste0("&markers=color:blue|label:S|",
"40.702147,-74.015794&markers=color:green|label:G|40.711614,-74.012318&markers=",
"color:red|color:red|label:C|40.718217,-73.998284"), destfile = "MyTile1.png");
tmp <- PlotOnStaticMap(Map, lat = c(40.702147,40.711614,40.718217),
lon = c(-74.015794,-74.012318,-73.998284),
destfile = "MyTile1.png", cex=1.5,pch=20,
col=c('red', 'blue', 'green'), add=FALSE);
PlotOnStaticMap(Map, lat = c(40.702147,40.711614,40.718217),
lon = c(-74.015794,-74.012318,-73.998284),
lwd=1.5,col=c('red', 'blue', 'green'), points(x = 40.702148, y = NULL ), add=TRUE)
看到 PlotOnStaticMap
中的 points()
语法了吗?
