  MOY = TRUE,
  vect_year_elim,
  type_ref,
  type_other,
  fish_power,
  title
)

Arguments

data_IA	data table containing the year in the first column, and the different AI series on the following ones
MOY	if TRUE, then mean_3years is run
vect_year_elim	vector containing the years to delete. Else, empty vector c()
type_ref	Select AI for standardisation.
type_other	Select others AI
fish_power	A vector containing technological creep for each AI in type_other. Not applied if equal zero.

data(data_IA_JABBA)
data_IA_test <- data_IA_JABBA %>%  dplyr:::select(c(annee, ScientificSurvey_SEN, Artisanal_SEN))
mean_ai(data_IA=data_IA_test, MOY=T, vect_year_elim=c(), type_ref = "ScientificSurvey_SEN", type_other = "Artisanal_SEN", fish_power = c(0.05), title = "1st Try")
