coords2Lines: 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 SpatialLines.

Usage

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

data

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

match.ID

logical, see SpatialLinesDataFrame.

...

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

Value

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

Examples

# NOT RUN {
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")

mapview(sln1)

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