Dear Members,

if I am using readShapePoly and spTransform for producing polygons, but the result polygons are not in right position. 
How can I rotate it clockwise for example like 5°?
 
natSHP.sp <- readShapePoly("nro2.shp", proj4string=CRS("+init=epsg:26978") )
nat2.sp <- spTransform(natSHP.sp, CRS("+proj=longlat +ellps=WGS84"))

Where can I get more detail information about the different options of CRS("+init=????") 

Best Regards,
Jian
