In inbo/n2kanalysis: Generic Functions to Analyse Data from the 'Natura 2000' Monitoring

Select the observations based on the average of a factor

Description

The negative binomial average of the Count variable is calculated for each level of variable. Only the levels which are equal or larger than threshold times the maximal average (in the original scale) are retained.

Usage

select_factor_threshold(observation, variable, threshold)

Arguments

observation	the data.frame with observations
variable	the name of the factor
threshold	the minimal threshold

Examples

observation <- data.frame(
  Count = c(100, 101, 50, 51, 1, 0, 0, 0),
  LocationID = factor(rep(1:4, each = 2))
)
select_factor_threshold(observation, "LocationID", threshold = 0.05)
