Transform coordinates from a specified source to a specified
target map projection. This uses the 'PROJ' library directly, by wrapping the
'PROJ' package which leverages 'libproj', otherwise the 'proj4' package. The 'reproj()'
function is generic, methods may be added to remove the need for an explicit
source definition. If 'proj4' is in use 'reproj()' handles the requirement for
conversion of angular units where necessary. This is for use primarily to
transform generic data formats and direct leverage of the underlying
'PROJ' library. (There are transformations that aren't possible with 'PROJ' and
that are provided by the 'GDAL' library, a limitation which users of this
package should be aware of.) The 'PROJ' library is available at
<https://proj.org/>.

Recursive lists in the form of R objects, 'JSON', and 'XML', for use in
teaching and examples. Examples include color palettes, Game of Thrones
characters, 'GitHub' users and repositories, and entities from the Star Wars
universe. Data from the 'gapminder' package is also included, as a simple data
frame and in nested and split forms.
