SpatialLines {sp} | R Documentation

## create objects of class SpatialLines or SpatialLinesDataFrame

### Description

create objects of class `SpatialLines` or `SpatialLinesDataFrame` from lists of `Lines` objects and data.frames; extract list od Lines from a SpatialLines object

### Usage

    SpatialLines(LinesList, proj4string = CRS(as.character(NA)))
    SpatialLinesDataFrame(sl, data, match.ID = TRUE)
    as.SpatialLines.SLDF(SLDF)
    getSLlinesSlot(SL)
    getSLLinesIDSlots(SL)

### Arguments

`LinesList` | list with objects of class Lines-class
`proj4string` | Object of class `"CRS"`; holding a valid proj4 string
`sl, SL` | object of class SpatialLines-class
`data` | object of class `data.frame`; the number of rows in `data` should equal the number of `Lines` elements in `sl`
`match.ID` | logical: (default TRUE): match SpatialLines member Lines ID slot values with data frame row names, and re-order the data frame rows if necessary
`SLDF` | SpatialLinesDataFrame object

### Value

`SpatialLines` returns object of class `SpatialLines`; `SpatialLinesDataFrame` returns object of class `SpatialLinesDataFrame`
