This function uses a modified version of code from the following 'r-sig-geo' post by Roger Bivand: https://stat.ethz.ch/pipermail/r-sig-geo/2013-April/017998.html
1 2 3 4 5 6 7 8 | seg = toSeg(build[1, ])
plot(seg, col = sample(rainbow(length(seg))))
raster::text(rgeos::gCentroid(seg, byid = TRUE), 1:length(seg))
# Other data structures
toSeg(geometry(build)) # SpatialPolygons
toSeg(boston_sidewalk) # SpatialLinesDataFrame
toSeg(geometry(boston_sidewalk)) # SpatialLinesDataFrame
