Method "tests" for Class "ages"

Description

Test if a set of ages belongs to a given number of populations or alternatively find out the most probable number of populations within a range.

Usage

## S4 method for signature 'ages'
tests(object, nbmin = 1, nbmax = NULL, level = object@level, verbose = TRUE)

Arguments

object	an object of type ages as produced by the function calculateAges()
nbmin	a numeric. Minimum tested number of populations.
nbmax	a numeric. Maximum tested number of populations.
level	a numeric. Confidence interval level. Default is equal to object@level, i.e., to the level of confidence used to calculate the ages.
verbose	logical. Activates the verbose mode.

Details

The function successively tests all values from nbmin to nbmax and keeps the smallest accepted one (returns an error if all supplied values are rejected). In this case, the output value is an object of class ageTests.

If nbmax is NULL, the results are kept even if the test is rejected. In this case, the output value is an object of class oneAgeTest.

The performed tests are those described in Montel et al. (1996).

Value

An object of class ageTests or oneAgeTest depending on the value of nbmax (see section "Details").

Usage

tests(object, nbmin=1, nbmax=NULL, level=object@level, verbose=TRUE)

Methods

• signature(object = "ages"): an object of type ages as produced by the function calculateAges().

• ...: other arguments passed to the method's function (see section Usage)
