Converts a genlight object into genepop format (and file)

The genepop format is used by several external applications (for example Neestimator2 (http://www.molecularfisherieslaboratory.com.au/neestimator-software/). So the main idea is to create the genepop file and then run the other software externally. As a feature, the genepop file is also returned as an invisible data.frame by the function.

Usage

gl2genepop(
  x,
  outfile = "genepop.gen",
  outpath = tempdir(),
  pop_order = "alphabetic",
  output_format = "2_digits",
  verbose = NULL
)

Arguments

x: Name of the genlight object containing the SNP data [required].
outfile: File name of the output file [default 'genepop.gen'].
outpath: Path where to save the output file. Use outpath=getwd() or outpath='.' when calling this function to direct output files to your working directory [default tempdir(), mandated by CRAN].
pop_order: Order of the output populations either "alphabetic" or a vector of population names in the order required by the user (see examples) [default "alphabetic"].
output_format: Whether to use a 2-digit format ("2_digits") or 3-digits format ("3_digits") [default "2_digits"].
verbose: Verbosity: 0, silent or fatal errors; 1, begin and end; 2, progress log; 3, progress and results summary; 5, full report [default 2, unless specified using gl.set.verbosity].

Value

Invisible data frame in genepop format
