These functions are stubs that don't do anything in R, but represent callback functions in SLiM. Call these functions as part of a slim_block call to specify that the code is designed to work with a particular callback. Most callbacks are designed to be called within SLiM under special circumstances, and will have 'pseudo-variables' that are accessible only inside that particular callback. See help files for individuals callbacks listed below for more details. Available callbacks are:
