This function corrects the slope of the settlerrecruit curve so that the collapse point of the spatiallyexplicit population model corresponding to the connectivity matrix agrees with that of the global nonspatiallyexplicit model. Uses the method in White (2010).
1 2  settlerRecruitSlopeCorrection(conn.mat, slope = 1, natural.LEP = 1,
critical.FLEP = 0.35, use.arpack = TRUE)

conn.mat 
a square connectivity matrix. 
slope 
slope at the origin of the settlerrecruit relationship. Only
interesting to fix this argument if it is a vector of length =

natural.LEP 
value of lifetimeeggproduction (LEP), also known as
eggsperrecruit, in the absence of fishing. Can be a vector of length =

critical.FLEP 
Fraction of natural.LEP at which collapse occurs. Defaults to 0.35. 
use.arpack 
Boolean determining if calculation is to be done with

The slope argument corrected so that collapse happens when LEP is critical.FLEP * natural.LEP.
