error: Mat::rows(): indices out of bounds or incorrectly used
Error in coord_matches_sf(as.matrix(nodecoords %>% dplyr::select(.data$X,  : 
  Mat::rows(): indices out of bounds or incorrectly used

我正在使用从OSM数据创建的SF对象，无法运行SpatialLinesNetwork函数。与spDataLarge的bristol_ways数据进行比较时，它看起来还不错。就像bristol_ways对象一样，坐标系是WGS_84。我不确定超出范围的索引是指什么。从spatialLinesDataFrame到sf对象的转换似乎发生了一些事情。该操作适用于spatialLinesDataFrame，但是一旦转换为sf，就会引发此错误。

我还尝试将其投影到2264（北卡罗来纳州NAD83），并使用uselonglat = FALSE运行它。

索引超出范围SpatialLinesNetwork
