Seasonal encounter rate for the extension template

Applies a sinusoidal seasonal multiplier on top of the encounter rate computed by lower extensions and the base mizer calculation.

Usage

# S3 method for class 'mizerExtensionTemplate'
projectEncounter(params, n, n_pp, n_other, t = 0, ...)

Arguments

params: A MizerParams object of class "mizerExtensionTemplate".
n: Species abundance matrix (species × size).
n_pp: Resource abundance vector (full size grid).
n_other: Named list of other component states.
t: Current simulation time (years). The seasonal multiplier is 1 + amplitude * sin(2π t), which peaks at t = 0.25 and troughs at t = 0.75.
...: Additional arguments passed through the dispatch chain.

Value

A numeric matrix (species × size) of encounter rates, seasonally scaled.

Details

This method replaces the setRateFunction() approach used in single-user scripts. It participates in the S3 dispatch chain so that multiple loaded extension packages can each modify the encounter rate without overwriting one another.

Why `project*` methods instead of `setRateFunction()`

setRateFunction(params, "Encounter", "myFn") stores a single function name per rate. If two extension packages both call it for the same rate, the second silently overwrites the first. S3 dispatch via project* methods avoids this: each extension defines a method for its own marker class and calls NextMethod() to pass control down the chain.

Rules for every `project*` method

Always call NextMethod() — omitting it silently drops all contributions from lower extensions and the base mizer calculation.
Keep the same argument signature as the generic and include ... so extra arguments pass through to lower methods.
Do not call setRateFunction() in your constructor for any rate handled by a project* method in this package.
