Projected SpatialLinesDataFrame has a segment spanning the globe

Thanks much to you both--Edzer's suggestion does work to remove the 

vertex. Based on the input I managed an alternative, which is to correct the
original vertex to not pass 180 degrees longitude (it's currently at
180.0000004, which is apparently the problem):

ind = which(coastsCoarse <at> lines[[94]] <at> Lines[[1]] <at> coords[,1] > 

coastsCoarse <at> lines[[94]] <at> Lines[[1]] <at> coords[ind,1] = 180

Cheers,
Ryan

Please let me know where you learned that you could use coordinates() to
assign coordinates to a Spatial* object.
