Thank you Roger. Using
do.call("spRbind", myListOfSpatialPointsObjects)
do not work, but I can work around.

Its all quite simple I think (i.e. "hope"). Have
you used spTransform(rdgal)?
## here I have a file from a local group delivered

library(rgdal) # for map projection support; automatically loads sp

Thank you Edzer. I was hoping there was a simpler solution, but it's still
fairly simple.

Thank you Milton. I have already explored this source, without success.

Yes, but you will not like that call.
In R (package sp), each spatial data set can only have one single
projection. I'd suggest, in pseudo-code
- import the data into a data.frame
- for each UTM zone do:
select the locations
set their CRS
reproject to long/lat
- cbind the locations to a
Hi Renaud,
may be you find some solution reading last posts.

Dear all,
I have a big dataset (> 200,000 lines) of georeferenced locations where
the coordinates are given in UTM, spanning over several zones. Is is
possible to convert all the UTM coordinates into longlat WGS84 with a
single call ?
