Details

Considering C_{ay}, the catch in numbers at age a=1,...,A per year y=1,...,Y, obtained e.g. from the catch.n slot of a "FLStock" object, the computation of pay P_{ay} is:

P_{ay}=frac{C_{ay}}{sum_a{C_{ay}}}

Examples

data(ple4sex)
# compute catch proportions at age
ple4sex.pay <- pay(ple4sex@catch.n)
# fine tune 
ttl <- list(label="Catch proportion at age for Plaice in IV", cex=1)
yttl <- list(label="age", cex=0.8)
xttl <- list(cex=0.8)
ax <- list(cex=0.7)
# plot
bubbles(age~year|unit, ple4sex.pay,  main=ttl, 
        ylab=yttl, xlab=xttl, scales=ax)
