Error: Assigned data `distHaversine(dtrav)` must be compatible with existing data
我只是想用 longitude/latitude 点来计算行进距离。我有 2983223 行数据。我不断收到此错误，并且我的距离列在整个 df 中重复相同的值。
library(geosphere)
dtrav <- matrix(c(df$start_lng,df$start_lat), c(df$end_lng, df$end_lat), nrow=2983223,ncol=2)
df$distance <- distHaversine(dtrav)

您应该分开起点和终点矩阵，否则 distHaversine 计算行之间的距离，这导致 n 行的距离为 n-1，因此出现错误消息。
df$distance = distHaversine(cbind(c(df$start_lng,df$start_lat)),
cbind(c(df$end_lng, df$end_lat)))
