Split a line into multiple lines

+ Source: R/split-line.R +
split_line.Rd
+
+ +
+

This function splits a line into multiple lines at specified points.

+
+ +
+

Usage

+ 
split_line(line, split_points, tolerance = 0.01)
+
+ +
+

Arguments

+ + +
line
+

A LINESTRING object.

+ + +
split_points
+

A sfc object containing points to split the line.

+ + +
tolerance
+

A numeric value representing the maximum distance +between the line and the split points. If the distance between a +split point and the line is greater than this value, the point +will not be used to split the line.

+ +
+
+

Value

+

A sfc object containing the split lines.

+
+ +
+

Examples

+ 
library(sf)
+
+# Create a line
+line <- create_linestring(0, 0, 5, 5)
+
+# Create a set of points
+split_points <- st_sfc(
+  st_point(c(0.0, 0.0)),
+  st_point(c(3.5, 3.5)),
+  st_point(c(1.0, 1.0))
+)
+
+# Plot the line and split points
+plot(line, lwd = 2)
+plot(split_points, add = TRUE, pch = 3, lwd = 2)
+
+
+# Split the line at the specified points
+split_lines <- split_line(line, split_points)
+
+# Plot the split lines
+plot(split_lines, lwd = 2, col = c("#E69F00", "#56B4E9", "#009E73"))
