NOTE: this repository is no longer being updated. I no longer maintain the RMark package. The new maintainer is Simon Bonner. See https://github.com/sjbonner/RMark
This package provides a formula based interface for MARK which does analysis for a wide range of capture-recapture models. To use RMark, you need to install MARK.
You'll also want to read the Gentle Introduction to MARK by Evan Cooch and Gary White.
Beyond the help in the RMark package, additional documentation is in Appendix C in Cooch and White. You can find additional documentation here.
The RMark package is available on CRAN and you can download the CRAN version directly from R.
