Demerelate (version 0.8-1)

Fis.calc: Calculation of $Fis$ empirical and bootstrapped values

Description

Internal function of Demerelate and F.stat to calculate $F_{is}$ values from empirical datasets. Performing randomization statistics and preparing output.

Usage

Fis.calc(tab.pop, iteration, number.loci, object, 
              directory.name, out.name)

Arguments

tab.pop

Data.frame following format of inputformat only column three and four are used for calculations

iteration

Number of replicates for bootstrap statistics

number.loci

Number of loci in tab.pop

object

Whether tab.pop is an object or file

directory.name

Name of the directory results send to

out.name

Filename of the output

Value

• Function returns a list containing the following information:
• output.fis[[1]]
  Empirical $F_{is}$ values according to Nei 1983.
• output.fis[[2]]
  Empirical $F_{is}$ values according to Weir and Cockerham 1984.
• output.fis[[3]]
  p values for significance for $F_{is}$ values according to Nei 1983.
• output.fis[[4]]
  p values for significance for $F_{is}$ values according to Weir and Cockerham 1984.
• Additionally, a file is generated containing all these information if file.output is set as TRUE or alternatively when directory.name and out.name are given.
• SummaryPopulationout.name.txt
  Combined output with different $F_{is}$ metrices and allele\genotype frequencies
