Method propagate

Source: R/genericMethods.R, R/FLQuant.R
propagate.Rd

Methods to extend objects of various FLR classes along the iter (6th FLQuant) dimension. Objects must generally have a single iter to be extended. The new iterations can be filled with copies of the existing, or remain as NA.

Usage

propagate(object, ...)

# S4 method for class 'FLQuant'
propagate(object, iter, fill.iter = TRUE)

Arguments

object

Object to be propagated.

fill.iter

Should first array be copied to others? Defaults to FALSE.

iters

No. of iterations in output.

Generic function

propagate(object, ...)

Examples


# An FLQuant with one iter (dim(flq)[6] == 1)
flq <- FLQuant(rnorm(80), dim=c(4,20), quant='age')

# can now be extended along the `iter` dimension, with
#' copies of the first
propagate(flq, 100)
