Changes in version 0.1.2 (2026-04-10) - Maintainer e-mail address changed. Changes in version 0.1.1 (2026-02-15) - We do not import the 'scModels' R package anymore. Changes in version 0.1.0 (2024-03-27) - Typo fix in the document. - A paper describing the implementation details of this package is published in Statistics and Computing. Description field is updated. Citation information is added as well. Changes in version 0.0.8 (2023-11-07) - Corrected the way of linking a C++ function. - Minor typo fix in the document. - Added ORCID ID. Changes in version 0.0.7 (2023-04-06) - Patch version, handling three additional issues checked by CRAN: 1. clang-ASAN, gcc-ASAN: For the function 'rvMFangle', the case where kappa=0 was not handled in the previously submitted code. That is why the second example failed. However, I should note that 'rvMFangle' is wrapped by the function 'rvMF', and the case where kappa=0 is handled in the 'rvMF' function. That is, the function 'rvMFangle(...,..., kappa=0)' is never called by the 'rvMF' function. I revised the document, and clarified that the parameter 'kappa > 0' for the function 'rvMFangle'. I therefore replaced the previous example on the 'rvMFangle' function with kappa = 0.1. Versions 0.0.5--0.0.7 had lack of explanation on this issue. 2. valgrind: As noted by the CRAN, the source of error was not freeing the malloced (or calloced) array. I now free them at the end of the function. I checked this with my linux + valgrind, and no error occurs anymore. - Fixed the C++ code to prevent memory leak issue. Changes in version 0.0.4 - Changed examples in the manual. Changes in version 0.0.3 (2023-03-01) - Ligatures 'ff' fixed. Changes in version 0.0.2 - Added a NEWS.md file to track changes to the package. - Added README.md to .Rbuildignore file. - Ligatures 'ff' fixed.
