The Waypoint R package enables conversion, validation, formatting and and elegant printing of geographic positional coordinates and waypoints (paired latitude and longitude values). Coordinates and waypoints may be converted easily and rapidly between (i) decimal degree, (ii) degrees and minutes, and (iii) degrees, minutes and seconds formats.
You can install the development version of Waypoint from GitHub with:

Create “coords”
objects in each format with as_coords().
Create “waypoints”
objects in each format with as_waypoints().
Convert “coords” and “waypoints”
objects between decimal degrees, degrees and minutes, and degrees,
minutes and seconds formats with convert().
Assign latitude and longitude attributes to individual coordinate
values within “coords” objects with latlon<-().
Ensure values within “coords” and
“waypoints” objects are valid geographic locations with
validate() and identifies individual invalid values with
review().
Use format() and print() S3 methods for
neat formatting and printing of objects of classes “coords”
and “waypoints”.
Waypoint uses high performance C++ code seamlessly
integrated into R using Rcpp to enable rapid
conversion and formatting of large coordinate and waypoint datasets.
While every effort is made to ensure this package functions as expected, the author accepts no responsibility for the consequences of errors if your map shows a city in the middle of the ocean, if your boat runs aground, or even if your aeroplane crashes into the mountain.
