Dear R FAQ Team :p
So I have been able to use the readOGR function, could anyone transfer to its
maintainer a request to add writeOGR in the "see also" section of help?
Anyway, after having done that for my shapefile, I tried to deal with the
points I had to plot on, here is what I tried:

The underlying shapelib code will not be maintained, anmd
maptools::readShape* will be deprecated very soon. Always use
rgdal::

Thanks Barry,
That's it… Sorry if my question was too simple… I'm not a geograph, I'm a
molecular biologist… so I'm not used to these packages … I started from the
simple script I had for normal maps… (and it is monday, brain isn't fully
operational!)

Probably because you've used readShapeSpatial which ignores projection
info from shapefiles...

Hi,
At a guess, your Front dataset doesn't have a CRS set, so
spTransform() doesn't know what to transform *from*.
See the examples in ?spTransform for the whole process, including
setting the CRS for your data.

Hi,
I need to convert some geographical coordinate it UTM.
First I have a shapefile:
Front<-readShapeSpatial("ISL_adm0.shp")
class(Front)
[1] "SpatialPolygonsDataFrame"
then… I tried this after googling:
DataUTM <- spTransform(Front, CRS("+proj=utm +zone=27 +north +datum=WGS84"))
