doconstC calculates and plots projections under a constant catch

Description

doconstC merely combines the functions gettraject, doproject, makedeplet, and plotconstC to simplify the process of conducting projections using constant catches. Compare this with separately using the functions gettraject, doproject, makedeplet, and plotconstC in sequence, which is all that dococnstC does.

Usage

doconstC(
  inR1,
  projn = 5,
  constCatch = 100,
  lastyear = 2017,
  limit = 0.2,
  target = 0.48,
  console = TRUE,
  intensity = NA
)

Arguments

inR1	the R1 object that is within the list generated by run_cMSY.
projn	the number of years of projection with a default of 5
constCatch	the constant catch to be applied to each successful trajectory
lastyear	the final year of the known catches and biomass trajectories
limit	the depletion level acting as the limit referencepoint
target	the depletion level used as a biomass target for the species.
console	logical, should results be printed to the console. Default =TRUE
intensity	the value that defines the density of trajectories required to give rise to full colour; default = NA which implies grey

Value

a matrix of the all years with the proportion < 20 proportion > 48 the proportion of trajectories that were increasing relative to the lastyear of data.

Examples

## Not run: 
data(invert)
fish <- invert$fish
glb <- invert$glb
reps <- 10000  # one would run at least 20000, preferably more
answer <- run_cMSY(fish,glb,n=reps,sigpR=1e-6)
out <- doconstC(answer$R1,projn=5,constCatch=150,lastyear=2017,
                limit=0.2,target=0.4)
str(out)

## End(Not run)
