我正在学习使用传单包在 R 中编程。我想给图标一个角度，并尝试使用以下代码：

m <- leaflet()
m <- addTiles(m,urlTemplate = "http://xdworld.vworld.kr:8080/2d/Base/201310/{z}/{x}/{y}.png")
m = m %>% setView(127.074167,34.456806, zoom = 9)
arrowIcon <- makeIcon(
  iconUrl = "arrow.png" 
  ,iconWidth = 100, iconHeight = 100 
  ,iconAnchorX = 25, iconAnchorY =25
)
arrowIcon <- makeIcon(
  iconUrl = "ARROW_B2.png" 
  ,iconWidth = 100, iconHeight = 100 
  ,iconAnchorX = 25, iconAnchorY = 25
)
offset = 0.00 # zoom 10-> 0.03, 9->0.06, 8 -> 0.12, 7 -> 0.24
m_lat = 34.45 + offset
m_lon = 127.07 - offset …
