| Description: | Creates a header only package to link to the 'CGAL' (Computational Geometry Algorithms Library) header files in 'Rcpp'. There are a variety of potential uses for the software such as Hilbert sorting, K-D Tree nearest neighbors, and convex hull algorithms. For more information about how to use the header files, see the 'CGAL' documentation at https://www.cgal.org. Currently downloads version 6.1 of the 'CGAL' header files. |

Check if CGAL header files exist in RcppCGAL package
Description
Check if CGAL header files exist in RcppCGAL package
Usage
cgal_is_installed()
Details
This function will perform a very simple check to see if the CGAL folder exists in the include directory and that it is non-empty. If the folder exists and is non-empty, the function returns TRUE; otherwise the function returns FALSE.
Value
logical value
Examples
cgal_is_installed()
Return CGAL version
Description
Return CGAL version
Usage
cgal_version()
Value
prints the CGAL version of the package
Examples
cgal_version()
Set the CGAL header file directory
Description
This package will set the CGAL_DIR environmental variable if you don't know how. Then you can re-install the RcppCGAL package and the installation should use your preferred source of the CGAL library. Note the cleaner functions will run automatically and replace the calls to std::err and exit in the C code. They have been tested on CGAL 5.6 so are not guaranteed to work with other versions of the CGAL headers.
Usage
set_cgal(path)
Arguments
path |
character vector. either a URL or system path |
Value
Invisibley returns TRUE if the CGAL_DIR variable was successfully set or or FALSE if it was not.

Examples
## Not run:
set_cgal("path/to/include/CGAL")
## End(Not run)
Unset the CGAL header file directory
Description
This package will remove the CGAL_DIR environmental variable.
Usage
unset_cgal(...)
Arguments

Not used at this time |
Value
Invisibley returns TRUE if the CGAL_DIR variable was successfully removed or or FALSE if it was not.
