[R] build a SpatialLines object from a list

[Ashraf Afana]

Hi all,I'm trying to build a SpatialLines object from a list that contains 124 river segments. Each segment in the list contains the x,y coordinates. I'm using the following code to create the SpatialLines object, but it just retrieves one segment. Any suggestions?

test.func = function(x){
     for (i in 1:length(x)) {        tt[[i]] <- x[i]; tt[[i]]  = Line(tt[[i]]); tt[[i]]  = Lines(list(tt[[i]] ), 'i')        tt1 = SpatialLines(list(tt[[i]]))           }    return(tt1)  }
Ashraf,
