LeMaRns

LeMaRns is an R package to set up, run and explore the outputs of the Length-based Multi-species model LeMans, focused on the marine environment.

Installation

You can install the released version of LeMaRns from CRAN with:

install.packages("LeMaRns")

Example

This is a basic example of how to set up, run and plot the resulting spawning-stock biomass:

library(LeMaRns)
NS_params <- LeMansParam(NS_par, tau=NS_tau, eta=NS_eta, L50=NS_L50,other=1e12)
#> Warning in .local(df, gdf, ...): The following columns of df do not match any of the species arguments and were therefore added to recruit_params:
#> a, b
effort <- matrix(0.25, 50, dim(NS_params @Qs)[3])
model_run <- run_LeMans(NS_params, years=50, effort=effort)
plot_SSB(NS_params,model_run)

lemarns's Issues

SSB!

library(LeMaRns)
NS_params <- LeMansParam(NS_par, tau=NS_tau, eta=NS_eta, L50=NS_L50,other=1e12)
#> Warning in .local(df, gdf, ...): The following columns of df do not match any of the species arguments and were therefore added to recruit_params:
#> a, b
effort <- matrix(0.25, 50, dim(NS_params @qs)[3])
model_run <- run_LeMans(NS_params, years=50, effort=effort)
plot_SSB(NS_params,model_run)

Through the above code to run out of the diagram(SSB), in addition to checking the ecosystem to achieve balance, is there any other role? Can it be compared with the observed data?
