Spatial aggregation of routes represented with sp classes
This function, largely superseded by sf implementations, still works but is not particularly fast.
overline_spatial(sl, attrib, fun = sum, na.zero = FALSE, buff_dist = 0)
sl |
SpatialLinesDataFrame with overlapping Lines to split by number of overlapping features. |
attrib |
character, column names in sl to be aggregated |
fun |
Named list of functions to summaries the attributes by? |
na.zero |
Sets whether aggregated values with a value of zero are removed. |
buff_dist |
A number specifying the distance in meters of the buffer to be used to crop lines before running the operation. If the distance is zero (the default) touching but non-overlapping lines may be aggregated. |
