R Documentation

Summarise Simulated Population

Description

Concise summary of a popn object.

Usage

## S3 method for class 'popn'
summary(object, collapse = FALSE, ...)
## S3 method for class 'summary.popn'
print(x, ...)

Arguments

object	popn object
collapse	logical; if TRUE multi-session popn objects are treated as a single open population
x	summary.popn object
...	other arguments (not used)

Details

By default each component of a multisession object is summarised separately. If collapse = TRUE then turnover and movements are collated across sessions, matching individuals by rownames.

Value

For summary.popn, an object of class ‘summary.popn’ with various components. For a multisession object and collapse = TRUE the descriptors include the numbers of new individuals (recruits) and lost individuals (deaths), and matrices showing the status of each animal in each session (‘status’ codes 0 not recruited yet; 1 alive; -1 dead) and movement from previous session if alive then (‘movements’).

    nsessions = 5, details = turnover)
