lk-methods: resample

In ejardim/FLMethLen: Prototype package for size based methods

Description

Resamples from a distribution to generate a frequency table

Simulates a normal density function from an FLQuant

Usage

  mixnorm(mn, sd, bin, left = T)

Arguments

object	an FLQuant
dim	dimensions of FLQuant to sample within, i.e. if equal to 2 then sampling is within year
size	sum of frequency disribution
replace	sample with replacement?, defaults to FALSE only useful if values in object are integers
mn	an FLQuant with means
sd	an FLQuant with standard deviation

Value

a FLQuant with simulated frequency distribution

an FLPar with expected probability for lengths-at-age

Examples

## Not run: 
  library(FLCore)
  data(ple4sex)

  apply(resample(catch.n(ple4sex)[,1:4],2,  100),2,  sum)
  apply(resample(catch.n(ple4sex)[,1:4],2:3,100),2:3,sum)
  apply(resample(catch.n(ple4sex)[,1:4],1:2,100),1:2,sum)
