In SOLV-Code/MetricsCOSEWIC: Metrics for COSEWIC status assessments.

calcPercChange

Description

this function applies a basic deterministic with various user options (e.g. log transform, gen avg smoothing, time window to use). For a single vector, use calcPercChangeSimple()

Usage

calcPercChange(
  X,
  gen.in = 4,
  slope.num.gen = 3,
  extra.yrs = 0,
  genmean.smoothing = TRUE,
  log.transform = TRUE,
  out.exp = FALSE,
  tracing = FALSE
)

Arguments

X	a data frame with Years x Stocks. Row labels are years, no missing years allowed, NA are possible, but will result in NA for
gen.in	= average generation time
slope.num.gen	number of generations over which to calculate the perc change
extra.yrs	to handle COSEWIC "extra year". default is 0
genmean.smoothing	if TRUE, apply the smoothSeries() function. default is TRUE
log.transform	if TRUE, log-transform the time series before calculating the smoothed series. default is TRUE
out.exp	if TRUE, take the exponent of the smoothed series before calculating the perc change. default is FALSE
tracing	if TRUE, print various diagnostics to the command line. default is FALSE
