The sp package has what you need. spTransform() will convert from lat/lon to other coordinate systems.
char2dms() will convert lat/lon coordinates formatted as you have them into numeric lat/lon values. You may wish to use as.numeric( char2dms( [your data] ) ) It will take some effort to get your data structured so that spTransform() will work with I. And I suggest asking further questions on r-sig-geo. -Don -- Don MacQueen Lawrence Livermore National Laboratory 7000 East Ave., L-627 Livermore, CA 94550 925-423-1062 On 7/24/14, 11:11 PM, "Suparna Mitra" <suparna.mitra...@gmail.com> wrote: >Hi >Hello >, > >Can anybody please let me know > how can I convert Lat/Lon data in coordinates in R.
