%description
Fitting dimension reduction methods to data lying on two-dimensional
sphere. This package provides principal geodesic analysis, principal
circle, principal curves proposed by Hauberg, and spherical principal
curves. Moreover, it offers the method of locally defined principal
geodesics which is underway. The detailed procedures are described in Lee,
J., Kim, J.-H. and Oh, H.-S. (2021) <doi:10.1109/TPAMI.2020.3025327>. Also
see Kim, J.-H., Lee, J. and Oh, H.-S. (2020) <arXiv:2003.02578>.
