Proportion of mega-spawners, re-cast to 'avoid' mega spawners so that 100% is the target

Description

Froese, R., 2004. Keep it simple: three indicators to deal with overfishing. Fish. Fish 5, 86-91. 1 - proportion of the length observations that are equal to or greater than 1.1*Lopt. Lopt obtained from LoptFunc

Usage

PmegaFunc(LifeHistoryObj, LengthCompObj, byGroup = FALSE)

Arguments

LifeHistoryObj	A LifeHistory object from fishSimGTG.
LengthCompObj	A LengthComp object
byGroup	A logical indicating whether quantity is to be calculated separately for each of multiple length comp groups (TRUE) or to length comp is to be pooled across groups prior to calculating quantity (default = FALSE). When TRUE, pooling is ignored if only a single group exists.

Examples

library(fishSimGTG)
PmegaFunc(fishSimGTG::LifeHistoryExample, fishLengthAssess::LengthCompExampleFreq, byGroup = FALSE)
