In flr/FLa4a: A Simple and Robust Statistical Catch at Age Model

predict for a4aGr

Description

Predicts ages or lengths using a growth class

Usage

## S4 method for signature 'a4aGr'
predict(object, ...)

Arguments

object	the a4aGr object
...	arguments to be passed to the rMvdc and copula methods

Value

a matrix object with lengths or ages

Examples

# Set up the a4aGr object and parameters for the marginals
mm <- matrix(NA, ncol=3, nrow=3)
diag(mm) <- c(50, 0.001,0.001)
mm[upper.tri(mm)] <- mm[lower.tri(mm)] <- c(0.1,0.01,0.00004)
md <- ~linf*(1-exp(-k*(t-t0)))
imd <- ~t0-1/k*log(1-len/linf)
prs <- FLPar(linf=58.5, k=0.086, t0=0.001, units=c("cm","yr^-1","yr"))
vbObj <- a4aGr(grMod=md, grInvMod=imd, params=prs, vcov=mm, distr="norm")
predict(vbObj, len=1:50+0.5)
predict(vbObj, t=1:20+0.5)
