R code to fit the mortality model

R code to fit the Siler mortality model to re-sighting data of male and female lions from two populations (i.e. Hwange National Park and Serengeti National Park, respectively). For running the analysis that is presented in the associated paper, download this file "runsModel.R" and the corresponding functions file "fcts01.R". Furthermore, please download the data file "datSH.txt". Save all files to the same folder. Set your R working directory to that folder using the corresponding line in "runsModel.R". Run the model by running "runsModel.R". When the model is finished, the model output will be automatically stored as an Rdata file to the working directory folder. There will be three output objects, which store the output pertaining to the three model start ages. The three output objects will be a composite name of the nature: outFrom"model start age"_"version".Rdata (e.g. outFrom1_01.Rdata for start age x = 1 and model version 01). Please see the documentation/comments in the code for further details on the starting objects, model fitting process, and the output objects.
