Dear all,
I know that it is a knew issue, but I have some troubles
on the conversion of UTM to Latlong of my shape file.
In fact, it apears to work but my input file is on South America Datum
(SAD69),
but I can´t find the how to indicate the datum. I tryed to include
"+datum=SAD69"
on the proj4string, but I received the following error: "unknown elliptical
parameter name"
Any help are welcome.
Best wishes,

proj4string=CRS("+proj=utm +zone=22 +units=m +south"))
SPll<-spTransform(SP, CRS("+proj=longlat +datum=WGS84"))
