ApplyPlanBsmooth: Applies the Plan B smooth approach.

In cmlegault/PlanBsmooth: Applies Plan B Smooth Approach to Biomass Index Data

Description

Smooths data (Year and Biomass Index) using loess, applies log linear regression to most recent three years, and retransforms back to estimate multiplier for catch advice.

Usage

ApplyPlanBsmooth(
  dat,
  od = ".\\",
  my.title = "",
  terminal.year = NA,
  nyears = 33,
  loess.span = NA,
  saveplots = FALSE,
  showplots = TRUE,
  nameplots = ""
)

Arguments

dat	data frame of Year and avg (the biomass index)
od	output directory where plots are saved (default=working directory)
my.title	title for time series plot with loess smooth (default = "")
terminal.year	last year used in smooth (allows easy retro analysis) (default = NA = most recent)
nyears	number of years to use in loess (default = 33)
loess.span	proportion time series used in smoothing (default = NA, calculates span=9.9/nyears)
saveplots	true/false flag to save output to od (default=FALSE)
showplots	true/false flag to display plots in window (default=TRUE)
nameplots	added to start of saved files (default=""), spaces not recommended
