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

"coords2Lines"(coords, ID, data, match.ID = TRUE, ...)
"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.
