the package is compiled to run on R 3.0.1 but should work on older versions, email me if you have problems (ijonsen -at- dal.ca). after loading the package in R, type ?fitSSM to get help on how to use the package, examples with a supplied dataset are provided at the bottom of the help file. this help file does not cover all the functionality of the package. i'll make the necessary updates when i have time in the near future.
code used in older publications (2003,2005,2006) can be found on the fmap - future of marine animal populations - legacy website: fmap computer scripts.
disclaimer: no attempt has been made to make these older code snippets widely applicable to different datasets or to make them cross-platform compatible.
