coords2Lines {Orcs}

Convert Points to ⁠SpatialLines*⁠

Description

Create a ⁠SpatialLines*⁠ object from a Line object or set of point coordinates in one go, i.e. without being required to run through the single steps outlined in sp::SpatialLines().

Usage

## S4 method for signature 'matrix'
coords2Lines(coords, ID, data, match.ID = TRUE, ...)

## S4 method for signature 'Line'
coords2Lines(coords, ID, data, match.ID = TRUE, ...)

Arguments

coords

Line object or 2-column numeric matrix with x and y coordinates.

ID

character, see sp::Lines().

data

data.frame with data to add to the output ⁠SpatialLines*⁠ object (optional).

match.ID

logical, see sp::SpatialLinesDataFrame().

...

Further arguments passed on to sp::SpatialLines(), i.e. proj4string.

Value

If 'data' is missing, a SpatialLines object; else a SpatialLinesDataFrame object.

Examples

library(sp)

coords1 <- cbind(c(2, 4, 4, 1, 2), c(2, 3, 5, 4, 2))
sln1 <- coords2Lines(coords1, ID = "A")

coords2 <- cbind(c(5, 4, 2, 5), c(2, 3, 2, 2))
sln2 <- coords2Lines(coords2, ID = "B")

plot(sln1, col = "grey75")
plot(sln2, col = "grey25", add = TRUE)
