Create a birp_data Object from Count and Effort Matrices

Description

Usage

birp_data(counts, efforts, times, CI_groups = NULL, location_names = NULL)

Arguments

counts	A matrix of observed counts (J locations × K timepoints). Each row corresponds to a location and each column to a timepoint.
efforts	A matrix of observation effort with the same dimensions as 'counts'.
times	A vector of length K specifying the timepoints.
CI_groups	A vector of length J specifying the control-intervention (CI) group for each location. Defaults to a single group ('group_1') if not provided.
location_names	Optional names for the locations. Defaults to '"Location_1"', '"Location_2"', etc.

Value

An object of type birp_data

Examples

data <- birp_data(c(10,20,30), c(100,200,300), c(1,2,5))
