Usage

## S3 method for class 'ALKr'

object	An ALKr object.
length_classes	A vector with the length value to be used for each length class. Defaults to the row names of x, which must be coercible as numerics.
...	other arguments (currently ignored)

Value

A summary_ALKr object, containing the mean length-at-age, the variance of the length-at-age, and the proportion of the age class in the population, for each age class. The name of the method used to calculate the ALK and its parameters are also included.

Examples

data(hom)
cALK <- classic_ALK(hom$otoliths[[1]], fi = hom$F1992)
summary(cALK)
hhALK <- hoenig_heisey(hom$otoliths[[1]], fi1 = hom$F1992, fi2 = hom$F1993)
summary(hhALK)
