Extracting X and Y coordinates from dput data

Dear all;
I have tried "dput" function and I gave this output.

topo = readOGR("E:/New/..../Lake_Topo_1267_5.shp")#Read shape file
crs(topo) = "+proj=utm + zone=39 +datum=WGS84"

fil = tempfile()
dget1 = dget("fil")
An object of class "SpatialLinesDataFrame"
Slot "data":

 87  8

The data frame of the "topo" has the exact number of row of the slot ID of dput (87 rows). Now I can see that the X and Y coordinates for each row. But there is a point, for each Elevation there are more than one XY coordinate. What I am trying to do is: putting Elevation for each ID of the dput data, e.g. for the ID number 1 that contains 30 (for example) rows of X and Y I want to add the first value of the Elevation column in topo data frame. After this I can create a 3 columns data frame with X, Y and Elevation in order to reading it into R and creating DEM.
