Dear list,

I have a shapefile where the zone number of UTM has been placed as first digits of the x-values. So the bounding box is:
  min      max
x 33085892 33475738
y  5801128  6059362

I want to get rid of the 33 and thus extracted the coordinates from the SpatialLinesDataFrame and substracted the value:
coordinates(data) -> coords
length(coords) -> num_list
for(i in 1:num_list){coords[i][[1]][[1]][,1] -33000000 ->   coords[i][[1]][[1]][,1] }
coordinates(data) <- coords
Unfortunately, I get an error when trying to write back.

Any ideas how to accomplish this - may be there are also easier ways to change the coordinate system?!

Thanks for your help in advance,
Ralf
