🚀 Advanced section (optional, not evaluated)

The chunk below reproduces your two‑sex, 8‑class model from
Population dynamic model.R. It is collapsed and eval=FALSE
so the default knit ignores it. Feel free to enable and explore!

# ---- Two-sex 8‑class model (excerpt) ----
# 1. parameters
ages  <- c("JuvF","SubF","AdultF","OldF","JuvM","SubM","AdultM","OldM")
S     <- c(0.55,0.80,0.88,0.75,   0.50,0.70,0.75,0.70)
Fec   <- c(0,0,1.25,0,             0,0,0,0)  # females only

# 2. build 8×8 Leslie & project...
# (paste your existing loop or %*% calculation here)

# 3. plot total females, males, harvest vector, etc.
