## Select the North Sea cod (cod-347d) assessment data.frame
nscod <- ices.cod[["cod-347d"]]
## Get the Fmsy from the meta-data
fmsy <- as.numeric(attr(nscod, "FMSY"))
## Plot the F/Fmsy of North Sea cod
plot(nscod$Year, nscod$F / fmsy, type = "l", xlab = "Year", ylab = "F/Fmsy")
lines(nscod$Year, nscod$High_F / fmsy, lty = 2)
lines(nscod$Year, nscod$Low_F / fmsy, lty = 2)
