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
