statistics | R Documentation |

A set of performance statistics is provided, coded in the format that
`performance()`

requires. The statistics included in this list are as
follows:

An object of class list.

SB0: Mean spawner biomass relative to unfished.

SBMSY: Mean spawnwer biomass relative to SBMSY.

Ftarget: Mean fishing mortality relative to target.

FMSY: Mean fishing mortality relative to FMSY.

green: Probability of being in Kobe green quadrant.

red: Probability of being in Kobe red quadrant.

PSBMSY: Probability of SB greater or equal to SBMSY.

PBlim: Probability that spawner biomass is above Blim.

risk1: ICES Risk 1, mean probability that spawner biomass is below Blim.

risk2: ICES Risk 2, probability that spawner biomass is above Blim once.

risk3: ICES Risk 3, max probability that spawner biomass is above Blim.

C: Mean catch over years.

VarC: Catch variability.

PC0: Probability of fishery shutdown.

Each indicator is itself a list object, with three elements, the first two of them compulsory:

An unnamed element of class

*formula*, e.g.`yearMeans(SB/SB0)`

.name: A short name to be output on tables and plots, of class character, e.g. "SB/SB0".

desc: A longer description of the indicator, of class character, e.g. "Mean spawner biomass relative to unfished"
