od_coords2line: Convert origin-destination coordinates into desire lines

In stplanr: Sustainable Transport Planning

Convert origin-destination coordinates into desire lines

Description

Convert origin-destination coordinates into desire lines

Usage

od_coords2line(odc, crs = 4326, remove_duplicates = TRUE)

Arguments

odc	A data frame or matrix representing the coordinates of origin-destination data. The first two columns represent the coordinates of the origin (typically longitude and latitude) points; the third and fourth columns represent the coordinates of the destination (in the same CRS). Each row represents travel from origin to destination.
crs	A number representing the coordinate reference system of the result, 4326 by default.
remove_duplicates	Should rows with duplicated rows be removed? TRUE by default.

Examples

odf <- od_coords(l = flowlines_sf)
odlines <- od_coords2line(odf)
odlines <- od_coords2line(odf, crs = 4326)
plot(odlines)
x_coords <- 1:3
n <- 50
d <- data.frame(lapply(1:4, function(x) sample(x_coords, n, replace = TRUE)))
names(d) <- c("fx", "fy", "tx", "ty")
l <- od_coords2line(d)
plot(l)
nrow(l)
l_with_duplicates <- od_coords2line(d, remove_duplicates = FALSE)
plot(l_with_duplicates)
nrow(l_with_duplicates)
