Hi!
Suppose your data set is called nc1.df.
Then you can do:
library(rgdal)
nc1.wgs84 <- spTransform(nc1.df,CRS("+proj=longlat +datum=WGS84"))

Subject: [R-sig-Geo] converting from NAD83 datum to lat,lon
Hi all,
Is there a way/package/trick to convert the NAD83 formatted file to
lat lon format?
I downloaded the "Major Hydrography" dataset from NC,USA to plot
rivers into a NC map. However, the dataset is in NAD83 or in state
plane projection, but i need it to be in lat/lon.
Any help would be great.
Thanks
Migee
dataset can be found in:
http://data.nconemap.com/geoportal/catalog/search/resource/details.page?uuid=%7B2515713B-2CA0-476F-863F-61441A9D6F70%7D
The downloaded dataset consist of
hydromaj_arc.dbf
hydromaj_arc.prj
hydromaj_arc.shp
hydromaj_arc.shx
hydromaj_arc.txt
hydromaj_poly.dbf
hydromaj_poly.prj
hydromaj_poly.shp
hydromaj_poly.shx
