Samples along the year dimension

Description

A resample from an FLQuant object along the 'year' dimension is returned. The 'year' dimnames of the output object can be specified, although that is not needed if the resample is to be assigned in a slot.

Usage

yearSample(x, size = length(years), years, replace = TRUE, prob = NULL)

Arguments

x	An FLQuant object.
size	Number of samples (years), non-negative integer.
years	Optional vector to set as 'year' dimnames in output.
replace	should sampling be with replacement? Defaults to TRUE.
prob	a vector of probability weights.

Value

RETURN Description, class
