SpatialLines {sp} | R Documentation |
create objects of class SpatialLines
or
SpatialLinesDataFrame
from
lists of Lines
objects and data.frames; extract list od Lines from a SpatialLines object
SpatialLines(LinesList, proj4string = CRS(as.character(NA))) SpatialLinesDataFrame(sl, data, match.ID = TRUE) as.SpatialLines.SLDF(SLDF) getSLlinesSlot(SL) getSLLinesIDSlots(SL)
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 |
SpatialLines
returns object of class SpatialLines
;
SpatialLinesDataFrame
returns object of class SpatialLinesDataFrame
