pathmapping package for the R statistical computing language.
Developed by Shane T. Mueller and Brandon Perelman Dept of Cognitive and Learning Sciences Michigan Technological University
This package allows you to measure the area-based deviation between pairs of paths. It uses an optimization approach to provide robust area-based measures. It produces both an area-measure and a mapping between paths.

- Fix improper c R_init_pathmapping() init function to expose compiled functions.
- Compiled version of Cost_Area that is now used by default--approximately 60% speed-up.
Minor fixes to address compilation on sparc, fix some documentation, and fix a return value issue that will apparently be deprecated in the future.
- Documentation improved.
- Fixed a problem with array dimension names in CreateMap
- Added compiled function shoelace formula. This is not used, because it is a bit slower than special-purpose surveyor's formulae for 3/4 points, but is a lot faster than the general-purpose surveyor's formula.
- Version number updated.
- First release
