Arguments

year

An n-length numeric vector of observed years.

samp_depth

An n-length numeric vector of the number of trees.

num_defol

An n-length numeric vector of the number of trees experiencing defoliation.

perc_defol

num_max_defol

An n-length numeric vector of the number of trees experiencing their maximum level of defoliation (i.e., their most extreme negative growth departure).

perc_max_defol

An n-length numeric vector of the percent of trees experiencing their maximum level of defoliation (i.e., their most extreme negative growth departure).

mean_gsi

An n-length numeric vector of the average growth suppression index across all observed trees.

mean_ngsi

An n-length numeric vector of the average normalized (scaled) growth suppression index.

outbreak_status

An n-length factor or character vector that identified whether that year surpasses the designated thresholds for an "outbreak event". Threshold criteria are provided in outbreak().

Value
