Functions

args

The mp() function takes as input a named list called args. These are arguments of the MSE run, and determine the time frame, frequency of application and lags. Only one argument is required:

  • iy, intermediate year. Only required element in args. The first year in which the procedure is applied.

For all other, default values are generated acording to the om object dimensions, or from internal defaults, as follows:

  • y0, first year. Defaults to start of om.
  • fy, final year. Defaults to last year of om.
  • nsqy, number of years to use for status quo calculations. Defaults to 3.
  • it, number of iterations. Defaults to iterations in om.
  • data_lag, difference between final year of data and iy. Defaults to 1.
  • management_lag, number of years between year of year of application and implementation.
  • frq, frequency. How often is the procedure to be applied, and for how long is a recommendation valid. Defaults to 1.

All these values can be simply overiden by including them in the args argument to mp(). The complete list of arguments is available to every (???) function in any element in the MSE control. In addition, these year dimension nbames vector, generated inside mp(), can also be used in any module function:

  • vy, the years in which the procedure is to be applied, from iy to fy. A character vector.
