Dear all,


I am trying to put two plots created with two different shape files

on top of each other.


They have got different coordinates and I would like to change them
(reproject the shape files) in order for them to


be exactly on top of each other.


I know that there are packages but I didn't understand which commands
I have to use.



first shape file:

Object of class SpatialPolygonsDataFrame
Coordinates:
       min      max
x 112518.2 685444.5
y 219903.9 514862.9
Is projected: NA
proj4string : [NA]



second shape file:

Object of class SpatialPolygonsDataFrame
Coordinates:
       min      max
x 112521.4 685441.9
y 275473.5 570451.2
Is projected: NA
proj4string : [NA]


Does anyone know the answer to this?


Thank you very much for your help in advance!
